Updated: 

Kensington Palace has marked Father's Day by tweeting pictures of the Prince of Wales with his two sons, and the Duke of Cambridge with Prince George.

One photo shows Charles posing with a young William and Prince Harry with their heads and hands resting on shepherds' crooks.

In the second picture William lovingly embraces George at a children's party for military families during the September 2016 royal tour of Canada.

The accompanying tweet reads: "Happy Father's Day. Wishing all the fathers out there a very happy day."
