Has Trump and Starmer’s 'special relationship' turned toxic?

Is Donald Trump's threat to impose more tariffs on countries trying to block his plan to buy Greenland the last straw for the strained relationship with the UK?

Niall speaks to the UK's first national security adviser, Lord Ricketts, about the history of the alliance between the UK and the US and whether Sir Keir can successfully keep it intact, at this delicate moment in history.
