Nigel Farage was caught on camera telling Ukip supporters to 'bully people' into voting for Brexit today.

The Ukip leader took his open-topped double decker campaign bus to Dudley in the West Midlands to drum up support for leaving the EU.

As the bus moved slowly through the town centre, he told the crowd: 'Those who believe in an independent Britain, you are a part of the People's Army.

'Go out and persuade people, bully people, go down the pubs, the clubs, your family and get them to vote to take back our country. We want our country back.'

Liberal Democrat leader Tim Farron condemned Mr Farage for the 'deeply irresponsible behaviour,' telling MailOnline: 'This is what we've come to expect from Nigel Farage and his gang of Brexiteers.

'First he warned of violence on the streets if we stay in the EU, now he's urging his supporters to go out and bully people.

'All the economic evidence shows that leaving the EU would make Britain permanently poorer to the tune of £4300 a year for the average household.

'It's clear that the Leave campaigns have lost the argument and they're now resorting to bullying instead.'

Today's footage, filmed by the BBC's Black Country political reporter Rob Mayor, is the latest evidence of bullying in Ukip's Brexit campaign.

Last night it emerged that Mr Farage's Leave.EU group published the personal mobile numbers of officials in the rival Vote Leave campaign in an extraordinary outbreak of infighting between the two Brexit camps.

In an email to a public email list, Leave.EU urged supporters to call Vote Leave individuals - including Ukip MP Douglas Carswell - to demand Mr Farage be included in a televised EU referendum debate.

The email from Leave.EU, run by the divisive figure and major Ukip donor Aaron Banks, attacked the 'backstairs crawlers behind the creaking Vote Leave campaign' who had excluded Mr Farage from the EU debate at Wembley Arena, which will take place two days before June's referendum.

Vote Leave spokesman Robert Oxley was one of the individuals targeted and he reported several 'angry phone calls' but dismissed the act as classless.

On the campaign trail today David Cameron (pictured at Luton Airport this morning) warned that Brexit could increase the cost of family holidays by £230 a year, but Nigel Farage claimed the PM was 'pretty close to cheating' and predicted that attempts to frighten voters into remaining in the EU could backfire

On the campaign trail today, Mr Farage claimed David Cameron's warning about the danger of Brexit was 'pretty close to cheating' and predicted that attempts to frighten voters into remaining in the EU could backfire.

Walking through the marketplace in Dudley, he poured scorn on the Prime Minister's claims that a British exit from the EU could push up the cost of holidays.

As well as accusing Mr Cameron and Chancellor George Osborne of feeding the public 'a constant diet of lies' in their arguments for staying in the EU, Mr Farage claimed the two men were 'using the whole apparatus of state in a way that, frankly, is pretty close to cheating'.

COST OF HOLIDAYS COULD RISE BY £230 A YEAR IF WE LEAVE THE EU, DAVID CAMERON WARNS The Prime Minister (pictured at Luton Airport today) claimed voters' foreign trips are under threat from a Brexit vote Brexit would make family holidays to Europe £230 more expensive on average, David Cameron has warned. The Prime Minister claimed voters' foreign trips are under threat as he ramps up his EU referendum campaign despite a Tory backlash over scaremongering. Arguing that Treasury analysis suggests a Leave result on June 23 could trigger a 12 per cent slump in the value of the Pound, Mr Cameron said bills for accommodation, food, drink and other costs abroad would rise. But the latest salvo in the increasingly bitter EU battle will infuriate Eurosceptics who have dismissed the official assessment published yesterday as 'propaganda' and even 'b******s'. Some ministers are said to have threatened to resign in the wake of the document - which also claimed Brexit could cost up to 820,000 jobs - being released yesterday. Speaking to easyJet staff at an event in Luton today, Mr Cameron defended the way he had conducted the campaign so far and insisted the Conservative Party would not be torn apart. 'Do I believe at the end of this we can all come together and accept the result? Absolutely, I do,' he said. The premier said he was making a 'clear' case for the UK to stick with Brussels on 'patriotic', economic and security grounds. 'The big bold patriotic thing is to stay in the EU ...to fight for the world we want,' he argued. But he insisted there were also clear 'retail' reasons why the public should vote to remain in the union. Advertisement

Mr Farage - who took time to visit a shoe repair shop and eat pork scratchings in a family butcher's - conceded the Prime Minister's warnings about the economic dangers of Brexit were having a short-term effect on polls.

But he told reporters: 'In the end I just feel that all these threats may well backfire.

'This time last year Remain were a long way ahead. This time this year, they're a little bit ahead.'

Asked to comment on the Treasury's controversial forecasts yesterday that Brexit would spark a recession or devalue the pound, Mr Farage replied: 'Is there any evidence to say there won't be a recession if we stay in? The British economy is not doing that well.

'Our 2 per cent growth is funded by a population increase of half a million people a year and by massive Government borrowing.

'They talk about about the pound going down. The pound has been going down since July 2014. Britain is not in that great a state.

'But this isn't about economics. I can tell you we will be better off out, he'll tell you we'll be better off in. Ultimately this referendum is not about trade, it's not about money - it's about political union.

'Do we wish to remain part of a political union that makes the majority of our laws?'

Mr Farage, who was greeted by a 200-strong crowd waving Ukip banners, said he believed many Leave campaigners were not making strong enough arguments with the EU poll less than a month away.

The party leader said: 'It's all well and good to say we could have more money for the NHS but actually this referendum is about more than that.

'Our politicians have given away control of our country. Our message has got to be clear - we believe in this country, we believe in its people and we want out country back.'

During the latter part of an hour-long walkabout, Mr Farage was invited to comment on the Prime Minister's claim that Brexit could add an average of £230 to a family holiday, and on Treasury analysis of the possible impact of a Leave vote.

Mr Farage told news crews: 'How dare Cameron talk about the cost of holidays when it's him with air passenger duty that's put hundreds of pounds on a family going to Florida or Disneyland or anywhere else?

'He's the man that's made holidays expensive. We do not need a European Commission to have competitive air fares - it's so typical of Cameron to make the accusation for the very thing that he himself is guilty of.'

Turning his fire on the Treasury, the Ukip leader observed: 'I notice that this is the same Treasury that told us we should join the Exchange Rate Mechanism, which was a catastrophe.

'The same Treasury that thought joining the euro might be quite a good idea. The Treasury has been wrong and wrong and wrong again - and it's wrong this time too.

'It's just trying to scare people. Frankly, to use all the apparatus of state to try and frighten people is pretty despicable.'

The latest frantic day of campaigning came as a new poll showed the Remain campaign 13 points ahead.

Worryingly for the Leave campaign, the new poll found its strong base of men, pensioners and Tory voters are snubbing the Out campaign.

Sir Lynton Crosby, the polling strategist who masterminded David Cameron’s surprise general election last year, warned the campaign to leave the EU is ‘dwindling’ and has ‘failed to quell ongoing concerns about the financial and economic consequences of a Brexit’.

The ORB poll showed the Remain campaign on 55 per cent and Leave trailing on 42 per cent among those who said they will definitely vote

Since the ORB poll in March, support for Brexit has fallen significantly, with the Remain campaign now leading among key voter groups, including those over 65, men and Tory voters. The Brexit campaign enjoyed significant leads among each of these groups two months ago

The influential election guru singled out particular criticism for the Vote Leave, which is spearheaded by Mr Johnson, saying today's poll reveals the 'weaknesses of the campaign's organisation'.

However Mr Cameron's bid to keep the UK in the EU was dealt a blow when his former policy guru Steve Hilton accused him of 'pathetic scaremongering' after the latest warning on the cost of family holidays.

Steve Hilton, who masterminded Mr Cameron's bid for Downing Street, said the claim that family breaks to Europe could be £230 more expensive was 'like a parody'.

Mr Hilton, who quit Downing Street in 2012 to teach at Stanford University in California and is supporting Brexit, said the holiday price warning was another example of 'pathetic patronising EU scares' and both sides were treating the public like 'simpletons'.

'You've got to be kidding. It's almost like a parody,' he told Press Association.

'I just wish we could have a serious debate about the long-term future of how we want to be governed rather than this kind of nonsense.

'It just does not do anyone any favours. It just puts people off the whole political class'.

Rival EU campaigns make cringeworthy bids for 'youth' support – as one side drafts in East 17 and Alesha Dixon alongside Nigel Farage for a 'Brexit festival' and the other urges the young to get '#VOTIN'

Twitter users poured scorn on both sides of the EU referendum debate today as they launched toe-curling bids for youth support.

A video aimed at persuading 'the youth' to vote to stay in the EU in the referendum backfired. Set to a loud soundtrack of thumping house music, the Britain Stronger in Europe video slices scenes of young people living a party lifestyle.

The video, which repeatedly drops the letter G, flashes up words 'workin, ravin, chattin, roamin' before imploring viewers to get 'votin' in the June 23 referendum.

The Brexit side fared little better as it announced a 'Brexit festival' featuring 1990s hitmakers East 17 and Alesha Dixon alongside Nigel Farage on June 19.

Alesha Dixon has been recruited to appear alongside Nigel Farage at a Brexit festival on the final weekend before the crunch EU referendum as the Leave side try and boost youth support

Boyband 5ive had been announced as part of the line up - but then pulled out over the political nature of the event.

The 'youth' vote is seen as critical to both sides in the referendum battle as traditionally turn out among the young is low.

If either side were able to get young voters to the polls it is seen as potentially crucial to their campaign.

Slamming the Britain Stronger in Europe (BSE) effort, Twayna Mayne said: 'Just when you thought things couldn't get any worse somebody came up with #votin ...#EndofDays.'

Emma Brooke posted a picture of the campaign which shows an attractive young woman splashing around in the sea with the words 'Chillin, Meetin, Tourin, #Votin'. She added: 'Err guys @votincampaign. You do know that young people still use the letter 'g' right...?'

Charles Turner, a marketer, wrote on Twitter: 'If we're old enough to vote, we're old enough not to be patronised... another reason why I think the #votin campaign is a disaster.'

The Britain Stronger in Europe seeks to remind young voters the EU is good for their 'meetin' and 'learnin' as it bizarrely strips a series of words of the letter G

The video has a grand finale that reminds youngsters of the voter registration deadline of June 7 to ensure they can get 'votin' on referendum day

Other users poured scorn on the Brexit side.

Jacob Daniel was one of many to suggest East 17 playing 'Stay Another Day' would be 'awkward'.

Andy Gilder said: 'Alesha Dixon and 5ive playing a pro-Brexit festival? Presumably as examples of outdated institutions taking money but giving nothing back?

Celia Linnett said: 'Oh excellent, an anti EU festival to get down with the kids. Line up almost as shocking as the idea.'

Education minister Sam Gyimah, a Conservative MP campaigning to stay in the EU, said the BSE video is an attempt to reach out to the so-called easyJet generation.

Social media users did not hold back on their criticism of either side. The Brexit festival was mocked for having a lead act whose main song was 'Stay Another Day' while others said the intent of the festival was as 'shocking' as its line up

Extolling the virtues of the EU, and the new video, on The Huffington Post website, he wrote: 'And it is the young generation for whom the answer is most obvious: life is better in the EU.

'As the #VOTIN launch video points out whether it is 'learnin', 'travellin', 'sharin' - the 'easyJet generation' takes being in the EU for granted on so many levels, and reaps the biggest rewards from our membership.

'They will be the worst affected if Britain votes to leave, finding it harder to get a job, suffering the squeeze of lower wages and higher prices, and forfeiting their automatic right to work, study and travel abroad.'

Twitter users complained of being 'patronised' by the Britain Stronger in Europe coming with a reminder for them to get 'votin' - pointing out they can use the letter g as well as anyone else

He warned that the 'easyJet generation could quickly become the lost generation' unless they turn out and vote.

But the video was quickly seized upon by the Brexit-backing opposition who joined in the mockery.

Tory MP for Braintree James Cleverly, who backs Brexit, wrote on Twitter: 'Clearly someone in their 50s came up with the #votin 'youth' campaign.

'It's so bad I thought it was a parody by the #Brexit team.'

Head of communications for Leave.EU Ann Wigmore backed her own campaign's plans.

She said: 'We are delighted to be endorsing this event which we believe will be a fantastic finale to the referendum campaign.'
