The Labour Leader Jeremy Corbyn has met the prime minister to discuss the draft withdrawal agreement.

Labour sources said the meeting was on the process from now until the meaningful vote in Parliament - and that Mr Corbyn pressed on the importance of parliamentary sovereignty.

The meeting took place in the prime minister’s Commons office, and lasted 20 minutes.

Earlier this evening, the prime minister Theresa May's former chief of staff Nick Timothy branded the Brexit agreement "a capitulation".

Provisions on the environment and farming have not been legally sealed yet, but environmental lawyers say we can get an idea of what lies ahead from the Irish backstop agreement.

This suggests that:

1. UK environmental law will have to be at least on a par with the EU at end of the transitional period. After that the UK doesn’t have to accept new environmental laws from Brussels – but it mustn’t slide back
2. The UK will have an adequately-resourced independent environment watchdog, with the power to oversee public bodies and take the government to British courts
3. On farming, the UK has won its fight to reform agricultural subsidies to reward farmers for protecting the environment. It won’t be tied to the Common Agricultural Policy
4. The UK will continue to uphold two important environmental principles – the precautionary principle, and the "polluter pays" principle

The headline is that EU citizens and their families will continue to have the right to move to live and work in the UK (and vice versa) until the end of the transition period (December 2020).

Those that take up residence before the end of the transition period will be allowed to remain beyond transition, and if they stay five years they will be allowed remain permanently.

However once the transition period is over, the draft agreement does allow the UK to require EU citizens who stay on to apply for a new residence document.

The agreement says application forms for this residence status "shall be short, simple, user friendly”.

All this applies to UK citizens in EU countries too.

The draft agreement says that a country may ask people to “voluntarily” start applying for this residence status before the transition period ends.

Looking to the future, beyond the end of the transition period the 14-page Outline Political Declaration document says that the UK and the EU will aim to achieve:

• arrangements for temporary entry for "business purposes"
• visa-free travel for short-term visits
• cooperation on tackling illegal immigration

Amazingly, when you consider that immigration was one of the key issues during the referendum that led to Brexit, the word “immigration” only appears once in the draft agreement, and even then it is in the context of an “immigration document”.

But a large section of the draft agreement – Part Two – is dedicated to the rights of EU citizens to live in the UK, and UK citizens to live in the EU.

The UK will “take back control” of migration from the EU, but it will happen slowly.

In a written statement, the German Foreign Minister Heiko Maas said: "I’m very pleased that the lead negotiators of the EU and UK have reached an agreement for now.

"This is a big relief. After months of uncertainty we finally have a clear signal from Great Britain about how an orderly Brexit is going to happen.

"Still we have a way to go. It will need more steps and more work on both sides. Brexit remains a decision that we regret.

"Nevertheless we want to have as close a relationship as possible with our British friends.

"We made a big step in that direction. My special thanks to Michel Barnier and his team who, as lead negotiators for the EU 27 reached this result with tireless engagement.

"We will now together with other member states peruse the text carefully and decide in the European council. For us it’s important that the rules of the single market remain untouched. The single market is the central achievement of the European project."

Tonight, Jacob Rees-Mogg who leads the European Research Group of Conservative MPs described the deal to the BBC as a "major problem" for the government, saying it "destroyed trust" because promises had been broken.

"It will have to come to a vote in the House of Commons and if it is what we expect, I will vote against it and I expect many others will," he said.

"This does not meet either the result of the referendum or indeed the Conservative Party's manifesto promises which are very important and on which I stood for election.

As for the prime minister's own position, I have consistently said I'm in favour of changing the policy rather than the person, but there unquestionably comes a point at which the two become indistinguishable."

Speaking to the BBC, the Labour leader Jeremy Corbyn has said he doesn’t believe the Brexit agreement is in the national interest because it “doesn’t meet the needs of all parts of Britain” and “doesn’t give us a security of our trading relationship with Europe in the future”.

Mr Corbyn said Labour would announce tomorrow morning during the Prime Minister’s Commons statement whether they will vote against the agreement.

Pressed on what the party would do, he said: “We will measure it against our six tests and if it doesn’t meet the six tests, then we will vote accordingly.”

He said that from what he had seen so far, “we’ve not seen anything that meets those six tests”.
