Action Medical Research and celebrity supporter Davina McCall are calling on Paddington Bear supporters to celebrate his summer birthday on June 25.

Paddington, who also has a birthday on December 25, is the charity's official fundraising mascot and people are asked to take to social media sites to wish him Happy Birthday. The charity has also developed a Facebook quiz to test people's knowledge and those answering correctly will be entered into a prize draw to win a toy Paddington signed by McCall. Other supporters include Phil Spencer, Joanna Rowsell, Dermot Murnaghan and Tony Hadley.
