(26.05.2014) Amid fears among moderate Tories that the Eurosceptics will feel emboldened by the success of Ukip, the prime minister is making clear that he will block any attempt to invite the new Alternative for Germany (AfD) party into the Conservatives‘ pan-European grouping.

Cameron has told colleagues that he sets such store by his relationship with the German chancellor that he would never allow her opponents to join the Tories.
