Photos: Kate and William back on royal duties

The Duke and Duchess of Cambridge were back at work today after facing criticism for jetting off on a secret luxury ski break to the French Alps last weekend. William and Kate arrived at St Thomas Hospital, in London, this morning to visit mental health patients and campaigners to highlight suicide prevention.

Kate, 34, recycled a distinctive bright green Erdem coat previously worn on the royal tour of New Zealand in April 2014 and at the launch of the Tour de France in Yorkshire in July 2014. William looked causal in chinos. More pics below...
