Liberal Democrats leader Sir Ed Davey asked in the Commons: "It's already clear that under President Trump we won't be able to rely on the United States, sadly, to help ensure our security against Russian aggression, and that's why we strongly welcome the Prime Minister's decision to increase Britain's defence spending.
Sir Keir said he will "resist" the suggestion we have "choose between the US and our European partners" after Trump branded Ukrainian President Volodymyr Zelensky a “dictator” and appeared to cut him out of peace negotiations with Russian President Vladimir Putin.
During Prime Minister’s Questions he was challenged on whether Britain could still rely on the US under Trump as well as the Government’s plans to cut foreign aid to boost the UK’s defence spending.
The Prime Minister also reiterated his view that Ukrainian President Volodymyr Zelensky is a "democratically elected leader", adding the UK "has successfully been a bridge between the US and Europe for many, many years".
"But there is also a view that taking money from aid and development to spend on armaments and tanks makes people less safe, not more safe, because the desperation and the poverty that so often leads to warfare, is what aid and development money is supposed to counter.".
