There are green benches on either side of the House; members of the Government party occupy benches on the Speaker's right, while those of the Opposition occupy benches on the Speaker's left. There are no cross-benches as in the House of Lords. The Chamber is relatively small, and can accommodate only 427 of the 650 Members of Parliament—during Prime Minister's Questions and in major debates MPs stand at either end of the House.
