I'm not so sure about that squishy.
Whether remoaner, remainer, dreamoaners or Anna Soubry this is last chance saloon for the bitter and twisted.
Strangely I don't think there is a majority for... Anything. Might sound strange to say but it isn't entirely binary.
Brexiteers probably make up the largest individual grouping but likely only 30% of the commons. Next would be the single marketeers and customs union types, but then you have the eea fanatics and other niches. And the noisy second referendum and outright remainers of course.
Hence around five or six individual groupings, none of whom agree with each other on anything.
Any compromise you can think of doesn't really result in an identifiable majority. Certainly not one you could hang your hat on as hard line brexiteers would probably vote against anything watered down etc.
This could of course mean the bill might pass unamended, though I don't find that likely.
Also Jeremy Corbyn wielding the whip is nothing less than amusing as he never obeyed it himself.
The Bill was published today and one labour mp was really very angry that the plebs got to see it before he did.
Hence Labour have been passionately opposing something that they haven't actually seen yet since the general election. They need to get their ducks in a row, and are probably relying on the summer recess to study it and come up with something. 
I doubt any of this will be lost on the tories and I don't think anyone expected the second reading to be tomorrow / today.
If you are feeling there might be some shenanigans in the works then I broadly agree, I'm thinking that something somewhere has to be knobbled.
