A million-pound row barge, built specially to mark the 60th year of the Queen's reign, has been launched on the River Thames.
The 94ft vessel is ornately carved and decorated with gold leaf. It also features wood from sweet chestnut trees grown on Prince's Charles's private estate.
Later this summer, it will lead the flotilla of boats taking part in the Diamond Jubilee river pageant.
Including 18 rowers, it will carry 52 people.
The Queen will formally name the barge Gloriana when she visits Greenwich next Wednesday to open the relaunched Cutty Sark attraction.
