Hmm - I am not sure if he currently does. Remember he only needs a 40 vote swing, and recently he:
- has lost the support of every one of his predecessors. His snub of May last week was ridiculous - and May still has her supporters
- has lost Steve Baker and his zealots over the lockdown restrictions
He won't be far off a rebellion if his deal is too hot on alignment. And bare in mind too that a few of the Statutory Instruments still need NI consent, and now more than ever SF / DUP have him over a barrel. They need only hint at a break of the GFA and Biden / the House will mobilise to put the pressure on. And Merkel, astute as ever, got right out in front to hint very broadly at exploring an EU:US FTA again, should that happen we'll be cap in hand to anyone who will have us.
And based on this

I'd be amazed if the UKIM Bill survives in its current condition. I can't see it.
