Sir Keir Starmer says the UK will not solve its problems if it does not have the "maturity and leadership" to extend "a hand to our European friends".
Speaking at a press conference at the end of the European Political Community summit, the prime minister says "it is not just a good idea to work with our partners, it's essential”.
Sir Keir also announces £84 million worth of new funding to tackle illegal migration for projects across Africa and the Middle East.
