US President Joe Biden has said the "world is better" because of Queen Elizabeth in a moving tribute on the eve of the monarch's state funeral. He was speaking at Lancaster House after visiting Westminster Hall to pay his respects to the late monarch on Sunday evening.
Mr Biden arrived with his wife Jill at the lying in state shortly before 5pm on Sunday, ahead of his attendance at Monday's funeral.
They were joined by the US ambassador to the UK, Jane Hartley.
The president stood on the platform for around two minutes, taking in the scene, where he crossed himself and exchanged a few words with the first lady. He looked on with a sombre expression and put his hand to his heart before walking away.
