Liberal Democrats MP Ed Davey has written a letter to UK PM Keir Starmer calling for sanctions against billionaire Elon Musk over his 'fight back or die' remark at a far-right activist Tommy Robinson-led anti-immigration march. Sharing the letter on X, Davey also urged all leaders to condemn Musk's comments. Musk responded to this, saying, "You are a craven coward."
