With a big chunk of Labour rebels rowing in behind the government, it's worth looking again at the numbers needed in parliament to defeat Sir Keir Starmer.
Due to the size of his majority, a rebellion would need at least 83 Labour MPs to sink the PM's wishes - alongside every opposition MP.
Currently, it is thought around 60 Labour MPs are wanting to rebel against the government - and it's not clear which way the Conservatives will vote.
However, if we get even further into the minutiae, there are two opportunities for the rebels to go against the government.
One is to table an amendment which would kill the bill.
The other is to vote against the bill as a whole.
This first step will be supported by Labour rebels, and potentially others like the Liberal Democrats and Greens.
However, if this first attempt fails, it is the second step that could see the Conservatives voting alongside left wing MPs.
The Tories may vote against the bill as a whole for not going far enough on changes, while Labour rebels will be voting against it for going too far.
But again, the numbers required for this to actually defeat the government seem like they are potentially unreachable for rebels.
