WARSAW/BRUSSELS (Reuters) - Poland's prime minister indicated on Thursday she might refuse to endorse a declaration to mark the European Union's 60th anniversary unless it addresses Warsaw's concerns, but diplomats played down the threat.

The EU wants to put on a show of unity at its meeting in Rome on Saturday following Britain's decision to leave the bloc. Britain is expected next week to trigger Article 50 of the Lisbon treaty launching the divorce negotiations.
