The Treasury has conducted its annual indexation exercise of the cost of oral and written parliamentary questions so as to ensure that these costs are increased in line with increases in underlying costs. The revised costs, which will apply from 3 December 2008, the first day of the 2008-09 session, are:

oral questions £410

written questions £149

The disproportionate cost threshold will be increased to £750, also with effect from the 3 December 2008.
