LONDON—British Prime Minister Theresa May’s government was scrambling on March 17 to get support in parliament for her Brexit deal at the third time of asking, aiming to persuade doubters with threats and promises to avoid any move to oust her.
After parliament backed a move to delay Brexit, May still has only three days to win approval for her deal to leave the European Union if she wants to go to a summit with the bloc’s leaders on March 21 with something to offer them in return for more time.
