Sir Keir Starmer has said that a “landmark” new post-Brexit trade deal with the EU will be a “win win” for both sides.
The Government claimed the agreement will boost Britain’s economy by £9 billion by 2040.
But the Prime Minister risked a huge row over fishing and following European Union rules to ease trade across the Channel.
However, shrugging off accusations of Brexit “surrender” from the Tories and Nigel Farage’s Reform UK, Sir Keir said: “It’s time to look forward.
“To move on from the stale old debates and political fights to find common sense, practical solutions which get the best for the British people.”
Key points in the deal include:
* Trade rules will be eased to allow more UK exports of food, including sausages, to the Continent, and stop lorries full of produce being delayed at ports. But it will mean Britain following EU rules on food standards which is already being slammed by the Tories as making the UK a “rule taker”.
* EU countries will let Brits use eGates at airports, avoiding lengthy queues, and “pet passports” for UK cats and dogs will scrap the need for animal health certificates for every trip.
* But the Government has made a significant concession on EU trawlers to fish in UK waters, replacing annual negotiations with a more “certain” longer time period of 12 years.
* Plans for a “Youth Experience Scheme” for young Brits to be able to work on the Continent, and vice versa for EU citizens. It would be capped and time-limited, and be similar to existing deals with Australia and New Zealand. The word “mobility” has been replaced with “experience” as the Government insists it is not a return to freedom of movement.
* A defence and security pact, with an agreement allowing British firms access to a 150 billion euro (£125 billion) EU defence fund. How much the UK will have to pay into the fund was yet to be outlined.
* To catch criminals, talks will continue on the UK getting access to EU facial images data, on top of the existing arrangements for DNA, fingerprint and vehicle registration data.
The deal was unveiled at a UK-EU summit at Lancaster House, central London, on Monday after “going down to the wire”.
At a press conference, Sir Keir declared that "Britain is back on the world stage", with the EU deal following trade agreements struck with India and the US.
The Prime Minister said: "This is the first UK-EU summit. It marks a new era in our relationship.
"And this deal is a win-win. It delivers what the British public voted for last year.
"It gives us unprecedented access to the EU market, the best of any country outside of the EU or Efta, all while sticking to the red lines in our manifesto about not rejoining the single market, the customs union and no return to freedom of movement."
European Commission president Ursula von der Leyen said the deal was a "historic moment".
Speaking alongside Sir Keir at the summit in Lancaster House, she said: "We are turning a page. We are opening a new chapter in our unique relationship."
But both Conservative leader Kemi Badenoch and Reform UK leader Nigel Farage had already slammed the deal as a “surrender”, despite the details not yet being known, and indicated they would tear it up if they came to power.
Ahead of the details being announced of the 12-year fishing deal, Mr Farage said: "If true that will be the end of the fishing industry."
Mrs Badenoch said she feared the mobility scheme would involve a return to free movement “by the back door” and stressed: “We’re becoming a rule-taker from Brussels once again.”
Meanwhile, the Liberal Democrats urged not to be “dragged back” to “the Brexit wars of the past”, with Sir Ed Davey comparing Mrs Badenoch and Mr Farage to “dinosaurs fighting old battles”.
