Brexit: Where are we now? David Wood takes a look at just what's happened in the past few days

As I walked through Parliament this lunchtime, a Brexit backing West Country MP came over to me and said 'she must go'. They were talking, of course, about Theresa May.

Another one later told me the situation was, "a pathetic shambles".

The Prime Minister is spending the day clocking up the miles talking to various EU leaders to try and convince them to make her Brexit deal a little more palatable for doubtful MPs.

What she is hoping for is some wiggle room on the plan for the so-called 'Irish Backstop'. This is the device that could be implemented to avoid a 'hard border' in Ireland if trade talks take longer than the transition period.

Many MPs are concerned with the 'backstop' because it is impossible for the UK to end it independently, instead the EU must agree.

Why does this matter? Well it would see the UK having to align many of its rules with EU rules, but it would be the EU (without the UK's input) deciding on those rules.

Effectively, critics argue, this means we take rules from the EU without being able to make them.

Brussels has made it clear it is not willing to renegotiate the EU exit deal, which suggests the Prime Minister will come back without anything significant enough to convince any doubters.

That said, I have spoken to a number of Conservative MPs who desperately want to back the PM but can't with the current deal. They're hopeful she can get a few more sentences from the EU to help her get a deal through.

What there does seem to be broad agreement on amongst the Conservative MPs I have spoken to is that Mrs May is at her weakest right now - and anyone plotting to replace her needs to act in the next 24 hours to stand a chance of forcing her to quit as PM.

But there is something else that is worrying moderate Conservative MPs at the moment, and that is if Brexit (however it looks) doesn't happen then it could be the end of the Conservative party, and potentially faith in politics in general. Usually loyal and quiet MPs are becoming increasingly angry at the stale mate over Brexit and are looking for hope somewhere - and few are finding it.

A word used by so many MPs in recent days and weeks is 'depressing'.

They want to talk about policies away from Brexit but can't, and they want to deliver on the Brexit referendum but can't agree on how that looks.

They know they have a big decision to make but few can agree on what that decision should be, hence the stale mate.

In a time when many are looking for inspiration it seems few are finding it anywhere in Parliament.
