BRUSSELS (Reuters) - There is no formal agreement yet among European Union leaders on a deal to keep Britain in the 28-nation bloc, a spokesman for the European Council President Donald Tusk, who is leading talks on the matter, said on Twitter. "Still no agreement on new settlement for #UKinEU at 'British dinner'," the spokesman, Preben Aaman, wrote after the Lithuanian and Czech leaders, present at the meeting, tweeted that an agreement had been reached.
