European Union leaders have warned they will not tolerate Russian interference in their negotiations on closer integration with Ukraine and other Eastern European countries.

At the end of a summit in Lithuania, European Commission President Jose Manuel Barroso said any third-party involvement in negotiations between the EU and another state was unacceptable.

Mr Barroso said: "What we cannot accept is a condition on a bilateral agreement to have a kind of a possible veto of a third country. This is contrary to all principles of international law."
