MPs’ staff, travel and accommodation costs reached £103 million last year, up from £99 million the previous year and £95 million in 2009 – the peak of the parliamentary expenses scandal.

More than £80 million was spent on staff salaries and £11 million on office costs. The bill for accommodation, covering hotels, rented homes and utility bills, was £6.9 million, while £4.5 million were claimed for travel and subsistence.
