https://en.m.wikipedia.org/wiki/Withdrawal_from_the_European_Union https://en.wikipedia.org/wiki/Unite...of_Article_50_of_the_Treaty_on_European_Union your question is equal to asking can the usa remove the 2nd amendment from the constitution ? or can the usa outlaw Islamic religions ? technically the answer is yes but what the people want and will accept is 2 completely different issues. you must remove the crystal ball gazing aspect of your question to move the possible answers into various logical discussions. one of those being "will the UK voters & citizens accept the UK government changing the law, revoking article 50 and not seeking an exit to the current EU trade agreement ? the answer to that is a resounding no. doing so would be equal to a dictatorship and create riots in the streets. however, what both sides are now looking for is some way to compromise without showing any compromise.
