They say hindsight is 20/20.

And some of Britain's most prominent politicians might be wishing they had not been quite so optimistic when they happily spoke about the country's prospects post-Brexit.

A pro-Remain group, called Led By Donkeys, has blown up tweets and statements by people including Theresa May, Liam Fox and Michael Gove, which have not aged well in a week where the prime minister's Brexit deal was voted down and the government scraped through in a vote of no confidence.

The billboard tweets include a statement Mrs May once made that remaining in the EU meant Britain would be more secure from crime and terrorism, and Dr Fox's claim that a Free Trade Agreement should be "one of the easiest in human history".

The billboards have been appearing around Dover in Kent, and the group says they are there to "remind the public of the statements and promises made to us by our MPs".

A spokesperson for the group said: "The news cycle is so fast nowadays, we forget what our leaders once said.

"If they want us to trust their judgment as we enter the choppy waters of Brexit it's right that we remind ourselves of their record."

The group asked people on Twitter to help decide the best tweets for the billboards, and those chosen have been voted for by Twitter users.

The top-voted quote was by Jacob Rees-Mogg, who in 2011 said: "We could have two referendums. As it happens, it might make more sense to have the second referendum after the renegotiation is completed."

The spokesperson said: "The idea - like most half-decent ideas - came in a chat down the pub.

"We were talking about whether Cameron would one day delete his 'chaos with Ed Miliband' tweet, and someone said: 'Let's turn it into a Tweet You Can't Delete.' It went from there."

The posters have also been put up in London and Essex and the group says it has spent about £400 on the project.

They admit permission hasn't always been sought but said they were "discerning" about what they covered up.

Boris Johnson is set to be the group's next target, with the group calling him "a treasure trove of hypocritical piffle".
