UK pharmaceuticals rose in early trading after speculation mounted President Barrack Obama's healthcare reforms could be thwarted by the Republicans.
News that the party had taken an extra seat in Massachusetts, giving it enough seats in the Senate to block Obama's proposals, buoyed the sector worldwide.
