After three years of debate them, the future Brexit might all come down to a straight fight in parliament and I hope very much now.

Speaking of elected representatives that my fellow MPs in Westminster do now come together to get Brexit done.

We have 650 MPs in the House of Commons, but only 639 of them actually vote.

Boris Johnson then needs 320 MPs to back his plan On Saturday on we leave the European Union, there are 287 conservative MPs.

All will be told or whipped in parliamentary language to vote for the deal that includes 28 members of the E R G group who support or harder Brexit and refused to back Theresa May's deal.

Some may not end up voting for it this time, but let's assume they do.

Boris Johnson is still short, so where does he find the numbers to get him over the line?

Well, not from the SNP applied or the greens there are likely to vote against as other Liberal Democrats and the Independent Group for Change.

Crucial head could be the 10 MPs from the D.

U P in Northern Ireland, there still insisting they will vote against the deal.

But there are two other groups that could be won over 1st 23 former members of the Conservative Party.

Most were expelled last month for voting to stop a no deal Brexit.

Some, though not all, are likely to back the government this time.

Then there is the Labour Party itself.

Leader Jeremy Corbyn has called this new deal even worse than Theresa.

May's plan does nothing to deal with a lot of concerns that we've raised during truce, amaze premiership, his about erase the bottom in rights and protections.

But there are still a small number of Labour MPs in the constituencies with a large leave vote who may disagree on vote with the government.

Boris Johnson needs to convince enough of these, perhaps with a handful of independent MPs to bolster the numbers.

It does look very tight a lot.

My even depends on whether some MPs vote against his plan or decide to abstain as in don't vote either way.

If that happens then the maths gets even more complicated, but it could just tip the balance in favor of the prime minister's deal.
