New portrait is released to mark Queen's 90th birthday
A photograph of the Queen and the Prince of Wales has been released to mark the end of the monarch's 90th birthday year.
The previously unseen picture, taken by fashion photographer Nick Knight in May, shows the mother and son in the White Drawing Room at Windsor Castle before the final night of the Queen's celebrations at the Royal Windsor Horse Show.
Charles, wearing a black dinner jacket, is smiling at his mother, who's dressed in a sea green and dove grey brocade dress by Angela Kelly.
The Queen turned 90 in April and later celebrated with a service of thanksgiving and a picnic on The Mall for 10,000 revellers. Mr Knight said: "It was a great pleasure and an honour to photograph Her Majesty The Queen and HRH The Prince of Wales at Windsor Castle. I wanted to create a modern portrait that showed warmth and humanity as well as strength and tradition."
