A pro-Brexit group is arranging protests
@ActionBrexit describe themselves on Twitter as a "new, direct action group." They say their aim is to "organise and coordinate action against those whose intention is to delay/stop Brexit."
They are organising a series of road blockades and "go slow" events this weekend, where motorists cause hold ups on major routes.
The M5 has been named on a list of possible locations, although it seems a specific event has not been organised. Someone has suggested the M5 at Junction 30, Exeter and the group has retweeted asking if anyone can help.
