"A 'bog standard' backbench MP is paid a salary of £60,675 a year. They get 18 weeks holiday a year, and can participate in a generous final income pension scheme.
They can claim up to £90,505 as a staffing allowance, and many use this to 'employ' members of their own families. They are also entitled to an Incidental Expenses Provision of up to £21,339 per annum, and an Additional Costs Allowance of up to £23,083 a year, to cover nights spent away from home.
For the year 2006/07, the average expenses claim for each MP was an incredible £135,773." ~ The UK Libertarian Party
