Boris Johnson has "totally capitulated" on fishing in the EU trade deal negotiations, but both sides have compromised, EU diplomatic sources have claimed. On Thursday Mr Johnson finally accepted the bloc’s final offer of returning 25 percent of the value of fish caught in UK waters to British fishermen. It was a “big move”, sources said, because he had been demanding 35 percent of the value of the catch. French officials claimed that the British had made major last minute concessions. The UK and EU settled on a five and a half year transition period before annual negotiations over fishing opportunities would begin. There was satisfaction in Brussels at having forced the prime minister into the climbdown but anxiety he will not be able to sell the deal to hardline Brexiteers in his party. “It won’t be a total victory. It never is,” an EU diplomat said. “I am a little concerned that London has not got the landing rights for the deal with its constituents.” “Whatever happens will be presented as a great victory. The Europeans will yawn,” another source said before confidently predicting that Mr Johnson has the European Research Group of MPs “in his pocket”.
