Pictures: Barack Obama arrives at Stansted Airport early due to threat of volcanic ash cloud from Iceland

US President Barack Obama arrived at Stansted Airport last night (Monday) after his flight was moved due to a threat of volcanic ash obstructing flight paths over the UK.

The President and his wife Michelle Obama flew into Stansted on Air Force One earlier than expected because of a volcanic eruption in Iceland. They were accompanied by an army of more than 500 staff and security.

Although a host of dignitaries, including Prince Charles and his wife Camilla, Duchess of Cornwall, were not present as expected, staff at the Essex hub, including airport boss Nick Barton, pictured, were on hand for the formal greetings.

It is the second time the US President has used Stansted. In 2009 he flew into the airport with Mrs Obama for the G20 Summit.
