The Duchess of Cambridge gave birth to a healthy, royal baby boy on Monday and they have just announced his name.

The new Prince of Cambridge arrived at 11.01am, weighing 8lb 7oz, Kensington Palace announced.

Kensington Palace said: "The Duke and Duchess of Cambridge are delighted to announce that they have named their son Louis Arthur Charles.

"The baby will be known as His Royal Highness Prince Louis of Cambridge."

He is the third child of William and Kate and younger brother to Prince George and Princess Charlotte.

The Prince of Wales has spoken of his delight at the birth of his latest grandchild and joked “the only trouble is I don’t know how I am going to keep up.”

William and Kate shared the name with the Queen and the rest of their family before making it public.

The new baby prince's great-grandmother the Queen, 92, is still at Windsor Castle for Easter Court, with the Duke of Edinburgh who is recuperating following a hip operation.

Born fifth in line, the baby is the Queen and Philip's sixth great-grandchild.
