was grilled about his new landmark deal with the European Union after granting them access to UK waters in return for an agreement to boost trade. The prime minister made a late concession on fisheries to allow the 12 years of ongoing access to British waters on status quo arrangements.
GB News's political editor Christopher Hope questioned the Labour leader over the deal, which critics believe have turned the UK into "rule takers" and "not rule makers".
He continued: "The Scottish Fisherman Federation say your deal is a horror show, far worse than Boris Johnson's botched Brexit agreement. Are they right? Have you been stitched up like a kipper by the European Union?"
The politician chose to repeat the driving principles behind the new deal, saying: "Does it bring down bills? I think it's really important to see the reaction of supermarkets to begin to answer that question because they are celebrating this because they know it will reduce prices."
He continued: "We all know how hard the crisis is bearing down on working people and therefore bringing down bills is hugely important. Does it boost jobs in security, in defence, steel of course and across all those areas affected by the SPS agreement? Energy and electricity are also within the scope of this.
"Does it take vital measures to help protect our borders? This goes beyond what we have been able to do."
The prime minister added: "I think it's important to remember, in relation to fishing, next year in the old arrangement, we didn't cease to have any EU fishing in our waters. We simply went to a year on year negotiation."
Sir Keir said this meant there was "no stability for anybody" but now fish can be sold into the European market, making a "material" difference in bureaucracy.
He went on: "I think it is important to emphasise again, the £360 million transformation fund to fishing communities which has never been put in place before."
After the meeting, the UK leader 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."
