JOHNSON'S PUSH IN PARLIAMENT
A vote is possible in the coming days, with the result uncertain. He also needs to enact the enabling legislation that would give the deal legal force.
If he can do that quickly, Britain either wouldn't need an extension or would need only a very short "technical" extension measured in weeks, not months.
WHAT HAPPENS IF PARLIAMENT DOESN'T COOPERATE?
If Johnson can't convince Parliament to quickly back the deal, it will be up to the EU to determine if it grants Britain another extension or sticks to the Oct. 31 date, which would mean the risky "no-deal" Brexit that many national leaders have been trying to avoid.
The EU isn't expected to reveal its answer in the coming days but an extension is seen as the preferred choice for many of the bloc's leaders despite their growing frustration with the stalemate in Parliament.
AN ELECTION IS LOOMING
An election may sound as if it would break the Brexit logjam, but it is possible no clear winner would emerge with a majority, so a new Parliament might be just as divided as this one.
Johnson complied with a law requiring him to seek a delay to the Oct. 31 deadline, but he followed his request with a letter to EU officials saying he didn't really think a delay was a good idea.
That infuriated opponents who believe he deliberately tried to frustrate the will of Parliament. Activists who have brought a case against Johnson in Scotland plan to return to court Monday; the dispute may end up in Britain's Supreme Court.
