Labour MEP Alfred Sant has asked the European Commission whether a definite date has been set to move 1,700 employees, including 50 Maltese, out of the Jean Monet Building in Luxembourg, where a large amount of asbestos was found.
Dr Sant asked the Commission, which leases the building, how many employees at the building had fallen ill as a result of asbestos.
He asked why had the Commission taken almost 20 years, from the first partial moves in 1995, to complete the move.
A statement issued by Dr Sant's office said that according to unofficial reports two people working at this building had already fallen ill as a result of asbestos.
The European Commission is expected to reply to Dr Sant in the beginning of January.
