Princess Catherine appears to be happy to be returning to the public eye.

The Princess of Wales has been pictured smiling in a carriage, alongside her three children, for the traditional Trooping the Colour parade.

It's her first public appearance since revealing her cancer battle.

Daily Mirror royal correspondent Russell Myers says the Princess released a statement before the event.

"She was enjoying getting back to some sort of normality - that's very important for cancer patients. She said that she's going to try and get to some engagements in the summer."
