Theresa May's move to open the way for a delay to Brexit could help her government avoid an embarrassing defeat on Wednesday when lawmakers reconvene to debate an amendable motion to her deal.

In doing so, she's managed to head off the opposition Labour Party, which announced earlier this week that it would support an amendment in Parliament ruling out a no-deal Brexit and supporting an extension to Article 50.

Labour declared yesterday that it would also back a second EU referendum, should its alternative to May's Brexit plan be rejected by Parliament on Wednesday.

These sudden policy shifts fall against the backdrop of major internal divisions in both the main parties.
