It was just as well the Duke of Cambridge gripped the Prime Minister's hand to steady her at a service to mark the centenary of the Battle of Amiens.

The centenary of a key turning point in the First World War was marked yesterday with a solemn service at Amiens Cathedral, according to the Daily Mail.

Twitter users reacted with astonishment to the PM's extra-low curtsy when she met Prince William yesterday.
