Prince William has made his first return to royal duties since Kate's cancer diagnosis went public. 

Last month the Princess of Wales revealed she's been receiving treatment amid wild internet speculation. 

The family has been away from the public eye but the Prince has returned to show support for a homeless food shelter. 

UK correspondent Vincent McAviney told Mike Hosking the public have been showing him and the Princess support. 

He says someone gave the Prince a 'get well soon' card and told him to look after Kate, which he replied he would.
