Nigel Farage has ripped into Prince Harry and Meghan Markle for their 'irrelevant' environmental campaigns and branded the late Queen Mother an 'overweight, chain-smoking gin drinker'.

The Brexit Party leader tore into the royal couple's decision to have only two children and claimed Prince Harry's popularity had 'fallen off a cliff' after meeting Meghan.

Mr Farage appeared to condone Harry dressing as a Nazi at a fancy dress party in 2005, saying he preferred the prince when he was 'getting into trouble' and 'causing all sorts of mayhem'.

But the former UKIP leader said the royal had turned into the 'Prince of Wokeness' after marrying Meghan.

Addressing a crowd of around 500, he said: 'Here was Harry, here he was this young, brave, boisterous, all male, getting into trouble, turning up at stag parties inappropriately dressed, drinking too much and causing all sorts of mayhem.

'And then, a brave British officer who did his bit in Afghanistan. He was the most popular royal of a younger generation that we've seen for 100 years. And then he met Meghan Markle, and it's fallen off a cliff.

During the rightwing conference, Mr Farage:

Said Harry's popularity had 'fallen off a cliff' since marrying to Meghan Markle

Claimed prince was more likable when he was 'causing all sorts of mayhem'

Branded Harry 'Prince of Wokeness' following his environmental campaigns

Described the Queen Mother as an 'overweight, chain-smoking gin drinker'

Called Prince of Wales 'Charlie Boy' and slammed his climate change views

WHAT DID NIGEL FARAGE SAY ABOUT THE ROYALS? 'Here was Harry, here he was this young, brave, boisterous, all male, getting into trouble, turning up at stag parties inappropriately dressed, drinking too much and causing all sorts of mayhem. 'And then, a brave British officer who did his bit in Afghanistan. He was the most popular royal of a younger generation that we've seen for 100 years. And then he met Meghan Markle, and it's fallen off a cliff. 'We've been told in the last week that Meghan and Harry will only have two children… and we're all completely ignoring, the real problem the Earth faces, and that is the fact the population of the globe is exploding but no one dares talk about it, no one dares deal with it, and whether Prince Harry has two kids is irrelevant given there are now 2.6 billion Chinese and Indians on this Earth. '[The Queen is] an amazing, awe-inspiring woman, we’re bloody lucky to have her. 'When it comes to her son, when it comes to Charlie Boy and climate change, oh dear, oh dear, oh dear. 'Her mother, Her Royal Highness the Queen’s mother was a slightly overweight, chain-smoking gin drinker who lived to 101 years old. All I can say is Charlie Boy is now in his 70s … may the Queen live a very, very long time. 'If I want the Queen to live a long time to stop Charlie Boy becoming king, I want Charlie Boy to live even longer and William to live forever to stop Harry becoming king.' Advertisement

'We've been told in the last week that Meghan and Harry will only have two children… and we're all completely ignoring, the real problem the Earth faces, and that is the fact the population of the globe is exploding but no one dares talk about it, no one dares deal with it, and whether Prince Harry has two kids is irrelevant given there are now 2.6 billion Chinese and Indians on this Earth.'

Mr Farage launched the scathing attack on the royals during the three-day Sydney Conservative Political Action Conference, where media members were banned.

He went on to praise the Queen for being 'an amazing, awe-inspiring woman', telling the conference 'we're bloody lucky to have her'. But he was not so kind about her son and mother.

He said: 'When it comes to her son, when it comes to Charlie Boy and climate change, oh dear, oh dear, oh dear.

'Her mother, Her Royal Highness the Queen's mother was a slightly overweight, chain-smoking gin drinker who lived to 101 years old. All I can say is Charlie Boy is now in his 70s … may the Queen live a very, very long time.'

It is not the first time Mr Farage has taken aim at Charles, having previously described his views on climate change as 'naive and foolish at best'.

In 2008 he was the sole MEP who refused to applaud a speech on global warming by the prince.

Many Twitter users jumped to Mr Farage's defence, claiming that he was well within his write to voice his opinions on the royals.

Richard Lane wrote: 'Did he say something that was false? His opinion on Charles' views are neither true nor false, just his opinion. And did the Queen's Mother chain smoke and drink gin? (I think you'll find she did).'

Royal commentator Robert Jobson said Mr Farage's comments were the 'epitome of ignorance' and said his attack on the Queen Mother was a 'cheap shot'.

He told MailOnline: 'I was surprised by Farage’s rant against the royal family given his stance on the importance of the Sovereignty of our nation.

'His comments are rude and unfounded; epitome of ignorance. But given his huge ego and overblown sense of self importance perhaps I shouldn’t be.

'I thought his remarks against Her Majesty late Queen Elizabeth the Queen Mother were particularly offensive and uncalled for. I am sure many will find his comments offensive.

'Especially given The Queen Mother’s life time of public service for Great Britain and her role alongside the King during World War II … not to mention she is no longer here to answer back. A cheap shot.

'He is undoubtedly an ego-centric exhibitionist who seems to says what he thinks the audience he is addressing wants to hear,

'I think his assessment of our Royal Family and what they do for this country, the realms and the wider Commonwealth is both misjudged, very unfair and ill informed.

'Perhaps at this time he should be talking up our country when overseas not insulting an institution that is at the heart of what is good about Great Britain.

Farage's spokesman said the comments were not meant as criticism of Elizabeth's mother, the wife of George VI who died in 2002, and the paper appeared to have taken off the cuff answers and changed their meaning.

'This is not an attack on the Queen Mother in the slightest. It's basically saying she lived until 101 so the queen, given that has a much better lifestyle than the Queen Mother, will live for a lot longer,' the spokesman said.

Actor David Schneider questioned Farage's comments and slammed him for condoning Harry dressing in a Nazi uniform

Labour MP David Lammy blasted Farage, telling the Brexit Party leader to lay off Meghan

Novelist Matt Haig also took aim at the former UKIP leader and questioned his patriotism

His comments come as Prince Harry faces renewed controversy over his trip to Google's 'green' summit in Sicily.

The Prince is thought to have given an impassioned speech about the environment and humanitarianism while barefoot in front of an A-List crowd who flew in on 114 private jets.

But Harry was said to have been flown into Palmero airport on a chartered plane, before a helicopter whisked him onwards to the luxury resort of Verdura for the summit.

Prince Harry is facing renewed controversy over his trip to Google's 'green' summit in Sicily amid claims that he stayed on a super-yacht. The Duke is pictured in on the shore of Lake McKenzie on Fraser Island during his tour of Australia with Meghan last year

Around 114 private planes are said to have landed at Palermo Falcone Borsellino airport for the top secret Google Camp

Prince Harry is believed to be just one among a host of celebrities and billionaires at the conference, which was blasted for hypocrisy

If he did travel via private jet, it would have put around three tonnes of carbon into the atmosphere - ten times more than going via commercial airliner.

The Prince then stayed on one of the giant super-yachts moored near the exclusive Verdura Golf and Spa Resort where the climate change retreat was held, according to reports.

According to experts, a 390ft super-yacht produces about 3.3 tons of damaging carbon dioxide each hour at sea by burning through around 200 gallons of fuel.

Environmental groups blasted the meeting for hypocrisy.

Tech giants and celebrities flocked to Sicily to show off their green credentials for the camp that focuses on global warming - but many failed to leave their private jets at home.

Around 114 fuel-guzzling planes are scheduled to land at Palermo, the nearest airport, between now and August 4.

Others brought their super yachts to the three-day conference which has A-lister attendees including Harry Styles, Katy Perry and Bradley Cooper.

When contacted by MailOnline, Buckingham Palace refused to confirm Prince Harry's attendance at the event or how he travelled to Sicily.

Mr Farage was introduced to the crowd in Australia as 'quite possibly' the next British PM, despite not being a member of parliament, and failing four times to be elected.

With the UK's exit from the EU just weeks away, the former UKIP leader also used his stage time to tear strips out of the EU and its outgoing president, Jean Claude Juncker - but admitted that he and Mr Juncker shared a rapport.

'I like Mr Juncker,' Mr Farage said, 'He's the only person I know that makes me feel that I haven't got a drink problem. I mean there's having a glass of wine at lunch but crikey!'

The Brexit party leader also called Australia's former PM Malcolm Turnbull a 'snake' as he savaged 'trendy, metro, liberal elite' leaders like David Cameron.

Mr Farage told the audience: 'Malcolm Turnbull … pretended to be a conservative but actually turned out to be a snake.'

He added: 'David Cameron was someone who was not conservative at all but a part of the trendy, metro, liberal elite masquerading as a conservative.'

Mr Farage backed Australia's new PM, Scott Morrison who was elected last summer, telling the audience: 'You've now got someone conservative, mainstream media [and] those in the middle of Melbourne and Sydney may not like him … But out where real people live, they voted for him.'

The former UKIP leader described how a conservative movement had gone global.

'These remarkable victories have happened for generally conservative-minded movements… there has been a revolt on the right,' Mr Farage said.

'Existing parties themselves have either changed, adapted, recognised that actually there are different thoughts and feelings in the middle of their countries that exist at the centre of their capital cities… or there have been new political movements.'

The outgoing president of the European commission is famously indulgent

He explained that this was because the parties which purported to be conservative were in fact, 'nothing of the kind.'

Mr Farage also made clear the intent of the Brexit Party should Britain's new PM fail to deliver on a timely withdrawal from the EU.

'Boris may not be 100 per cent nailed on to full independence for the United Kingdom but there is a new political reality,' Mr Farage said, 'What the Brexit Party have done is to completely reset the political agenda in Britain.

'The conservative government now know that if we we don't leave on the 31st of October, they as a political party, are finished.'

But Mr Farage conceded that when he was in Melbourne he'd thought 'the greenies had taken over' as 600 protesters rallied against him.

And protesters followed his movements in Sydney too. Footage from outside the Rydges Hotel showed around 30 demonstrators engaged in scuffles on the street.

At one point a man is doused in coffee as police officers hauled people away from the scene.

Tony Abbott, the Australian PM replaced by Mr Turnbull in 2015, was also at CPAC on its first day on Friday.

He described how Australia had 'lost its anchor posts' and said, 'they used to be anchored in the Christian faith. Faith is a gift, some people have, some people don't.'

Mr Abbott tore into legislation to decriminalise abortion in New South Wales.

Yesterday, controversial activist Raheem Kassam spoke at the conference about Australia's Labor party putting his life in danger when it tried to ban him from the country for criticising Islam.
