Prince George and Princess Charlotte are to have key roles when their aunt Pippa Middleton gets married in May. “Miss Pippa Middleton and Mr James Matthews are pleased to confirm their wedding will take place at St Mark’s Church, Englefield, on the morning of 20th May,” a statement said.

Unusually the announcement from Pippa and her fiancĂ© came via a press release from Kensington Palace. The statement confirmed that Miss Middleton’s niece and nephew will be a page boy and a bridesmaid.

It was also confirmed that the Duke and Duchess of Cambridge and Prince Harry will be among the guests, with the service attended by close family and friends. Royal watchers have wondered whether the younger royals would be involved in the wedding, especially as William and Kate are hugely protective of their children’s privacy, and would be conscious of upstaging Pippa on her big day.
