President Barack Obama will depart from Ireland to London earlier than planned on Monday after concerns of volcanic ash from an eruption in Iceland.

Due to a recent change in the trajectory in the plume of volcanic ash, air force one will depart Ireland for London tonight,” said White House Deputy Press Secretary Josh Earnest “The schedule for tomorrow will proceed as planned.

Obama was in Ireland on Monday as part of a six-day trip through Europe. Obama completed all appearances on his public schedule. He had planned to spend the night in Dublin.

He will spend two days in London, where he will make a state visit hosted by Queen Elizabeth II, meet with Prime Minister David Cameron and make an “anchor speech” of the trip before the U.K. Parliament.

After that, Obama will visit Deauville, France for the G8 summit, where he will hold bilateral talks with French President Nicolas Sarkozy, Japan Prime Minister Naoto Kan, and Russian President Dmitry Medvedev.

On Saturday, Obama will travel to Poland, where he will meet eastern European leaders.
