BRATISLAVA (Reuters) - The chairman of Slovakia's parliament said on Tuesday he had cancelled a meeting set for next Monday between the heads of parliament in European Union associate states and European Parliament officials, the official news agency TASR reported. Ivan Gašparovič was quoted as saying he called off the gathering in Bratislava because the chairman of the European Parliament, Jose Maria Gil-Robles, had decided not to attend. He did not indicate why Gil-Robles had declined to come to the Slovak capital. The meeting was supposed to have been the fifth in a series of talks between EU associate countries and EP representatives. Earlier this month TASR quoted officials from Gil-Robles's office as saying he had would not attend because the Slovak parliament had ignored a Constitutional Court ruling demanding the re-instatement of an expelled Slovak deputy. The court ruled in July that the Slovak parliament had violated the constitution by stripping František Gaulieder, a founding member of Prime Minister Vladimír Mečiar's Movement for a Democratic Slovakia (HZDS), of his mandate and said it was up to parliament to put things right. But the ruling coalition last September, in a session closely watched by western diplomats, voted against returning the mandate to Gaulieder.
