MPs' pay and pensions
On 24 May 2011 the Independent Parliamentary Standards Authority (IPSA) was made responsible for determining MPs' pay and setting the level of any increase in their salary.
The pension scheme for MPs is the Parliamentary Contributory Pension Fund (PCPF). Employee Contribution rates from 1 April 2012 are 1/40th accrual: 13.75%, 1/50th accrual: 9.75%, or 1/60th accrual: 7.75% of pensionable salary.
In the Commons, some MPs are paid more because of the special jobs they hold. For example, the Speaker and the Chairs of Committees receive an extra salary.
Most MPs who are also ministers in the Government are paid an extra ministerial salary.

Payments to Opposition parties
Some money is paid to those political parties represented in Parliament who are not in government. This is to help ensure that the Opposition and minority parties have enough funds to carry out their parliamentary role and to put across their views.
The amount given to each party depends on how many people voted for them at the last general election and how many of their candidates were elected. In the House of Commons this is known as 'Short Money'; in the House of Lords it is known as 'Cranborne money'.
