Pro-Brexit protesters are due to make their point to motorists on the M5 this afternoon with a rolling road block.

Traffic chaos is expected to blight the Friday night commute out of Exeter when the demonstration starts shortly after 5.30pm on Friday night from Junction 30 at Sandygate.

A protest group has urged lorry drivers to get involved with the protest, but it is expected that a whole host of different vehicles will be involved once the road block begins.

One organiser of the demonstration says their plan is to drive at 40mph in convoy across all three lanes of the motorway to Junction 27 for Sampford Peverell and Tiverton, before turning around and driving at the same speed on the southbound side of the carriageway back to Exeter.

The protest is part of a wider demonstration planned by the Brexit Direct Action group, which is aiming to orchestrate rolling blockades on a whole host of major motorway routes around the country.

The group is protesting against the prospect of Britain not leaving the EU by the Article 50 deadline of next Friday, March 29.

Brexit Direct Action wrote on Twitter: “Several social media groups have been in contact to ask if we’ll help gather support for a national truck drivers protest if #Brexit is delayed.”

Another tweet said: “Brexiteers all over the country are planning to bring this country to its knees by blocking the main arterial routes - M1, M6 M25, M62, A1, A55, M5, M4, M42, M55, M61, A66 etc.

“If you live close to one of these major motorways and are willing to take part then prepare to move at short notice.

“Don’t worry about the legal side of things, the national organiser is sorting that out.”

Devon and Cornwall Police have told Devon Live that they are fully aware of the campaign discussed on social media and "will continue to monitor before deciding what, if any, action will need to be taken."

A Highways England spokesman said the authority is also aware, adding: "Our focus is on providing a safe, reliable network for the millions of drivers who use our motorways and major A roads every day."
