Joining by video link, senior Tory MP Dame Cheryl Gillan says questions over trade in services, not addressed in the deal, need "urgent resolution".

Passing the bill will leave the country in a "golden position", Dame Cheryl adds.

He welcomes the "absence of tariffs" as well as level playing field and security provisions.

However he says he will vote for the deal and expresses the hope that it will provide a foundation to build a new relationship with the EU.

It brings an end to his own 29-year fight against the EU's growing powers, which started during the debates over the Maastricht Treaty in the early 1990s, he tells MPs. A vote against the government's bill is a vote for no deal with the EU, he adds.
The deal is "not perfect" but a "huge advance on where we might have been", Sir Iain, a leading Eurosceptic, argues.
Brexit was "never about being anti-European" but about being "good neighbours" to the EU, he says.

The Northern Ireland Assembly will too.
MLAs will meet at 12:00 GMT after the speaker approved a request from the first and deputy first ministers.
The motion will not be legally binding but "takes note" of the trade deal.
The Democratic Unionist Party, Social Democratic and Labour Party, and Alliance Party have all indicated their MPs will vote against the deal.

He says Northern Ireland will still be subject to some EU laws.
He confirms that his party will not be voting for the deal but insists his party has "no common cause with the petulant Remainers" describing himself instead as a "disappointed Brexiteer".
Image source, HoCSir Bill Cash and his long served eurosceptic colleagues gave the prime minister a boost yesterday when their powerful group of backbench Tory Brexiteers and serial rebels, said they will back the deal.
The European Research Group (ERG) instructed lawyers to examined the text in detail and concluded that it "preserves the UK's sovereignty as a matter of law".
The group said that the “level playing field” clauses "go further than in comparable trade agreements, but their impact on the practical exercise of sovereignty is likely to be limited if addressed by a robust government".
The level playing field clauses are rules aim to ensure that businesses on one side don't gain an unfair advantage over their competitors on the other.

He likens the PM to his "great hero", the ancient Athenian leader Pericles, calling him "first citizen of our country".
Johnson has achieved the "impossible", he tells MPs, and the country owes him its "deepest congratulations".
Joining remotely by video link, former Labour foreign secretary Dame Margaret Beckett says the PM's claim that there will be no non-tariff barriers "is not true".
She argues the deal will lead "to more rules, more bureaucracy, more regulations".
However she says MPs face a "Hobson's Choice - we accept this deal or we have no deal". To avoid a no deal she says she will vote to support the deal.
Image source, HoCConservative MP Sir Peter Bottomley, the Father of the House - its longest serving member - says today's vote is between the government's deal and no trade deal with the EU. Although he opposed Brexit in the 2016 referendum, he says he will back the government later.
It's imperative to make a success of the situation, he argues, and urges the SNP to stop using Brexit as a justification for Scottish independence.

Today won't be the last time Brexit is mentioned in Parliament, but it does mark an end to an extraordinary period of political turmoil.
There's no doubt the deal will be approved by MPs and peers given the government's hefty majority.
But the scrappy opening exchanges of debate show how the UK's relationship with the EU has the ability to divide opinion like nothing else.
It has dominated politics since long before the referendum in 2016 and set political parties against each other and themselves.
There may be relief on all sides at an end to the uncertainty, but there is no calm consensus about the future.
You only need to listen briefly to this parliamentary debate to know that Brexit remains divisive to the last.
Image source, HoCIan Blackford says that "this bad Brexit deal means businesses will be burden with mountains more bureaucracy."
However he says "the biggest betrayal of all is the broken promises to Scotland's fishing communities - this deal means less access to fish than under the current arrangements."
He also expresses disappointment that the Labour Party will be supporting the deal and accuses them of being "missing in action".
Concluding his speech he says Scotland's "future must be European."
"The only way to regain the huge benefits of EU membership is to become an independent state."
Back in the Commons, the SNP's Westminster Leader Ian Blackford began by telling EU citizens living in Scotland that "Scotland is your home, you are welcome."
He argues that Scotland was "European before it was British" and that Westminster is seeking to "end our access to European relationships".
He says the PM's deal "means a disaster of a deal, broken promises and economic vandalism".
And he accuses the government of either "drowning in delusion or simply putting on an act".

Image source, PA MediaAs well as today's debates in the House of Commons and in the Lords, MSPs in Edinburgh and Welsh Senedd members will also hold their own meetings to debate the new Brexit deal.
Wales' First Minister Mark Drakeford has called the agreement "thin and disappointing".
Senedd members will vote on the agreement, but it is symbolic, as they have no say on the Brexit legislation.
In Edinburgh, a motion in the name of First Minister Nicola Sturgeon calls for a "pause" to Brexit to consider the issue.
MSPs will debate the Scottish government motion which says parliament "does not consent to the bill".
Brexit deal: 'A thin deal for Wales' says first minister
Image source, HoCFormer Prime Minister Theresa May criticises Labour leader Sir Keir Starmer for saying he wanted a "better deal", adding that he voted against her own agreement with the EU.
She says she hopes there will be "little change" in co-operation with the EU in cross-border police work.
May says she is "disappointed" over the limited impact of the deal on financial services, arguing that no "groundbreaking" arrangement has been achieved.
And sovereignty "does not mean isolationism" and it's important to recognise the UK lives in an "interconnected" world, she tells MPs.
She urges the Commons to support the government's bill.
Brexit debate: 'We were told we could not have our cake and eat it'
Sir Keir Starmer says there is "very little protection" for services in the deal.
"The lack of ambition here is striking," he says.
He notes that there is "no recognition of professional qualifications" and only "a very thin agreement on short business travel which will make it harder for artists and musicians".
"Anybody who thinks that is an improvement really does need to look again," he says.
He then turns to tariffs and quotas. He says the PM has argued that his deal delivers zero-tariffs and zero-quotas.
"It does," says Starmer "for as long as British businesses meet rules of origin requirements, it does as long as Britain abides by level playing field measures."
"He is pretending he has got sovereignty and zero-tariffs and zero-quotas. He hasn't."
"The moment he exercises sovereignty, the tariffs kick in."
Image source, HoCStarmer now turns to the deal itself. He quotes the PM who said when he announced the deal that "there will be no non-tariff barriers to trade".
"He wasn't being straight with the British public - that is plain wrong.
"The PM knows its not true, every member of the house knows it is not true."
Boris Johnson gets up to say the deal "is a zero-tariff, zero-quota deal".
"Typical deflection," replies the Labour leader.
He says there will be an avalanche of checks and red tapes for businesses.
Starmer says "those voting no [to the deal] want yes - they want others to save them from their own vote."
"It isn't in the national interest to duck a question," he says adding that "Labour will vote to implement this treaty today to avoid a no deal and put in place a floor from which we can build a strong future relationship."
Labour leader Sir Keir Starmer has begun his response.
He says MPs face a "simple choice - do we approve the treaty with the EU or do we not".
He say anyone choosing the second option today "knows there is no time to renegotiate... there is no better deal coming".
"Choosing that option leads to one place - no deal."
He says the PM's deal is a thin deal but adds that "a thin deal is better than a no deal".
