A beaming Duke and Duchess of Cambridge have shown off their new prince to the world.
Less than seven hours after welcoming the latest addition to their family - a boy weighing 8lb 7oz - William and Kate briefly stepped outside St Mary's Hospital carrying the newborn, waving to the world's media and royal fans.
They then went back inside, re-emerging a few minutes later with the prince in a car seat. William fastened his son into the rear of a Land Rover Discovery before driving off.
Earlier, William brought Prince George and Princess Charlotte to St Mary's Hospital to meet their new brother.
News of the birth was announced in time-honoured fashion with a notice posted outside Buckingham Palace.
