Yet again, it has been an extraordinary week for MPs as we try to find a way through the Brexit chaos.

There was much excitement on Monday night when MPs voted on a motion, co-ordinated cross party, by former Tory Minister Oliver Letwin to remove control of Parliamentary business from the Government and allow backbenchers to determine the agenda. It won, ensuring that – to coin a phrase – parliament could take back control.

Wednesday then saw the first stage of a process of indicative votes on Brexit options with the second stage due to come on Monday.

While the Government was clearly unhappy with this approach, it was vital to see which options could command the most support among all MPs, with party lines blurred like never before.

The first stage results found there is no majority in Parliament for any alternative Brexit proposition but the motion to allow - as a minimum in law - for a permanent customs union with the EU narrowly lost by just eight votes.

Frustratingly, it would have gained a large majority had the SNP abided by its long-held policy and voted for it.

The winning proposition with the most votes, however, was for a confirmatory public vote on Brexit – something I have long championed.

The collaborative process will now be refined for Monday and we are all working very hard on a cross-party basis to find propositions that can command a majority.

At this time of constitutional crisis, working together between parties in the best interests of the country is the only way forward.

But where should the Labour Party go next?

For the record, the Labour Party is, and always must be, an outward looking internationalist party of remain. 

I was delighted that my party whipped in favour of a public vote. That is party policy and it is the right thing to do.

Next week, I hope my party uses every avenue available to put the national interest first and find a consensus on the way forward based on the indicative votes. 

Most importantly, any deal must be subject to a confirmatory vote of the public.

It is intellectually incoherent that the Prime Minister can have three or more shots at her defeated deal and Boris Johnson can change his mind on her deal to get into Number 10, but the public have had no say since 2016.

This is certainly not what Leave voters were repeatedly promised at the referendum. 

It’s time to break the parliamentary impasse and let the public back in.
