Polish Prime Minister Donald Tusk, fresh from being chosen as part of the European Union's new leadership team, held out an olive branch to Britain on Saturday, saying he was prepared to compromise on British concerns to keep the country in the EU.

Prime Minister David Cameron had publicly thrown his support behind Tusk this past week to be the new head of the European Council, representing the bloc's 28 governments, in hopes that the center-right Polish leader would help him push through reforms to the EU, which he sees as too centralized and bureaucratic.

Tusk's election follows Cameron's failed attempt to block former Luxembourg Prime Minister Jean-Claude Juncker from becoming the next leader of the EU's executive body, the European Commission, on grounds that he was too federalist.
