President Joe Biden welcomes Nato leaders to Washington on Tuesday for a summit which has become key to demonstrating he is capable of meeting the demands of the presidency for four more years.

Heads of state gathering to shore up transatlantic support for Ukraine in its battle against Russia are confronting the prospect of the return of Nato sceptic Donald Trump as Mr Biden tries to save his re-election campaign, which has been in a tailspin following a disastrous debate performance.
