A tentative Brexit deal with the EU is reached but it is not clear that it can win support of the Cabinet of prime minister Theresa May, even before it has any chance in the British parliament. March 29, 2018 is the 2 year period for negotiations to arrive at a deal with the EU. The pro-EU transport minister Jo Johnson resigned and called for a second referendum, saying that the decision in the first referendum to leave the EU was made because false prospects had been presented by the Leave EU campaign.
Because of the issue of Northern Ireland the U.K would remain indefinitely in the customs union, and this is opposed by the Leave EU supporters in the Conservative party government of prime minister May.
