Linda,
Yes I have read his tweet.
// Soft Brexit, Hard Brexit, massive pile of s***. Sloppy Brexit, messy Brexit, quit, quit, quit. //
To be honest, I do not know what it means.
Without knowing the context, and the timing, I do not know what he wants to quit quit quit. He has said he will not do anything to delay triggering Article 50, and that he will fight for the best Brexit deal for Stoke. Not exactly the actions of an avid Remainer.
