The society wedding of the year has been held in Britain, as Prince William's sister-in-law Pippa Middleton tied the knot with a wealthy financier.

Prince George and his sister Charlotte had roles, as page boy and flower girl.

The ceremony was held at a church west of London, followed by a private reception at the bride's parents' estate.

It's thought to have cost more than £300,000.

Air space over the venues was closed to prevent press crews sneaking photographs with drones.
