The Duke and Duchess of Cambridge were back in their formal wear as they visited a primary school in north London today (right), just 24 hours after donning their trainers for a session with marathon runners (inset). Kate looked elegant in a red skirt suit by Italian designer Luisa Spagnoli, a favourite ensemble which she has worn on a number on official engagements. The royals spent time meeting children outside Mitchell Brook Primary School, in Neasden (left) before attending an event to mark Children's Mental Health Week.
