William, Kate convoy involved in collision

A woman in her eighties is in a serious condition in hospital after an accident involving the Duke and Duchess of Cambridge's convoy.

William and Kate were on their way to a ceremony in Windsor on Monday when a marked police motorbike in their convoy was involved in a collision with the woman in southwest London.

The woman was taken to hospital in a critical condition, Scotland Yard said.

The duke and duchess are "deeply concerned and saddened" by what happened and have been in touch with the woman who they say is called Irene, Kensington Palace said.

The Independent Office for Police Conduct (IOPC) is investigating the circumstances of the collision which involved a motorcycle attached to the Royalty and Specialist Protection Command.

Kensington Palace said: "The Duke and Duchess of Cambridge were deeply concerned and saddened to hear about the accident on Monday afternoon.

"Their Royal Highnesses have sent their very best wishes to Irene and her family and will stay in touch throughout every stage of her recovery."

It is understood that the couple have sent flowers.
