Furious Brexiteers caused motorway chaos across the UK as they organised a lorry go-slow at rush hour after the EU exit date was postponed.

Traffic mayhem could be seen in Devon, Cornwall, Lancashire, Stoke-on-Trent, Hull and north Wales.

Brexiteers of Brexit Direct Action are calling for similar 'go slows' across the country as they declare their fury at Theresa May's negotiations. They claim that they have hauliers prepared across the land.

The protests come as the exit date was postponed til at least April 12, as it was revealed today MPs could vote on cancelling Brexit altogether.

Video footage showed the demonstration causing a slow down on the M6 in Lancashire, with drivers tooting their horns in fury and attempting to swerve through the slow drivers.

Devon and Cornwall Police said it had stopped the convoys on the A30 and M5 and prosecuted the two lead drivers of both convoys for careless and inconsiderate driving.

The force said it had spoken to the organisers beforehand and told them they were to ensure other motorists could pass them and not drop down to unsafe speeds.

But Inspector Si Jenkinson said that the campaigners had blocked both lanes of the A30 towards Cornwall and at least two lanes of the M5 northbound while travelling at speeds as low as 20mph on the motorway.

The Inspector Tweeted: 'We stopped 9 vehicles, the front two have been reported for inconsiderate driving the remainder given words of advice and allowed to continue their way and an appropriate speed.

'If they repeat their actions they are aware we have their details and prosecutions will follow.'

The Inspector said that his officers remained out on the road on the M5 to ensure traffic could flow freely after making two arrests.

There were also plans for go slows on the M20 and M25 in Kent scheduled for this evening.

A statement on the protesters' Twitter account says: 'BDA group believe that our government should fulfil their manifesto and EU referendum pledge to exit the EU on 29th March with either an acceptable Withdrawal Agreement, or WTO managed exit.'

They state their current activities include organising 'multiple hauliers' to take part in their go slows.

They add that they are against all forms of violence, including verbal and physical abuse.

The RAC advises that, while most motorways in the UK do not have an official minimum speed limit, 'travelling too slowly can be considered dangerous' and might attract attention from police.

Highways England tweeted: 'There have been a few issues but nothing of any major impact and at present everything is running as usual.'

Organiser Ian Charlesworth had said the protests could cause 'serious gridlock' and believes MPs and the Home Office 'will be looking at it', but added he does not know how effective the protests will be.

'The ultimate aim is to make sure come hell or high water that Britain leaves on March 29,' the 55-year-old said.

The protests have been organised through social media, with Mr Charlesworth's Facebook group containing more than 21,000 members.

After this weekend's protests he said a larger 'national event' is planned in London on March 29, should their demands not be met, which will coincide with the pro-Brexit March To Leave demonstration in Parliament Square.

After Article 50 was triggered the UK's withdrawal from the European bloc had been scheduled for March 29.

Theresa May failed to get her withdrawal agreement through on two separate occasions and will have a third attempt next week after getting a short extension from the EU to April 12.

Hard Brexiteers such as Jacob Rees-Mogg, Boris Johnson and Nigel Farage believe that May's deal does not fulfil the will of the people in any case.
