LONDON (AP) — The Latest on Britain's exit from the European Union (all times local):

The European Union's presidency thinks a series of developments over recent days have made it more difficult to predict what might happen at this week's summit of EU leaders, at which British Prime Minister Theresa May is expected to request a delay to Britain's departure date from the bloc.

Romania's European affairs minister, George Ciamba, whose country currently holds the rotating EU presidency, said "the biggest issue right now is that it's getting more foggy."

His comments come a day after John Bercow, the speaker of the House of Commons, ruled out a new vote on May's Brexit deal unless there are substantive changes. May was trying to win support from opponents who have voted against her deal on two occasions previously.

Ciamba said "we need to have more clarity from London. Clearly, there is no clarity."

EU leaders gather in Brussels on Thursday to weigh whether to grant Britain an extension on beyond March 29, and if so, for how long.

The British government is considering its response to the ruling of the speaker of the House of Commons that Prime Minister Theresa May cannot keep asking lawmakers to vote on the same European Union divorce deal they have already rejected twice.

Brexit Secretary Stephen Barclay told Sky News Tuesday that the Cabinet would give "serious consideration" to John Bercow's decision that the government could not bring the deal back for a third vote without substantial changes. May has been lobbying opponents in preparation for another vote on her plan.

Barclay says the government needs "to look at the details of the ruling."

"The fact that a number of members of Parliament have said that they will change their votes points to the fact that there are things that are different."
