King Charles III and Queen Camilla's state visit to the US dominates Tuesday's papers. The Times' top picture features the King and Queen greeted by US President Donald Trump and First Lady Melania Trump at the White House. The paper previews the King's address to the US Congress later saying he will deliver a "message of unity" and remind Washington of the shared "democratic, legal and social" values of the two nations. Elsewhere, Prime Minister Sir Keir Starmer is trying to shore up support ahead of a critical Commons vote on whether there should be a parliamentary investigation over his claims about the vetting of Lord Mandelson, the Times reports.
