Opposition MPs are expecting the one-day sitting of Parliament on May 18 to be a costly affair given the hotel, food and travel allowances allocated to the 222 parliamentarians to attend the truncated gathering.

This is particularly the case for the 57 MPs from Sarawak (31), Sabah (25) and Labuan (one) who have to fly to the federal capital to attend the sitting which is set to end just after the opening address by the Yang di-Pertuan Agong.
