London has real concern for Yemen LONDON, March 30 (UPI) -- There is "real cause for concern" about the political stability in Yemen after the country's presidential transition, a British minister said. The U.N. Security Council issued a presidential statement urging all political actors in Yemen to play a constructive role in the country's political transition. Long-time President Ali Abdullah Saleh signed a deal in 2011 to stand down following nearly a year of protests in his country. His vice president, Abdu Rabo Mansour Hadi, took control of the country after winning a one-man election in February. Some political figures in Yemen threatened to join the southern secessionist movement after Hadi's victory. The independent Yemen Post, meanwhile, says Arab leaders are pressing Saleh to stand down as the leader of the ruling General People Congress. "Yemen has made progress with the peaceful transfer of power to President Hadi in February's elections but the recent deterioration in political cooperation is a real cause for concern," British Minister for the Middle East Alistair Burt said in a statement. I call on all those with a stake in Yemen's future to work together to make political, economic and security reform a reality. The Security Council added that Yemeni authorities need to plan for a national dialogue conference and prepare for general elections in 2014.
