The title OP is a partisan statement, so there is no point in claiming now that you meant ALL politicians, bankers etc, ayse!
The Hagues live in a 3 bedroomed flat in the official London residence, not the whole house, and they have redecorated it at their own expense, which they could have charged to the taxpayer.
David Milliband preferred not to live there when he was Foreign Secretary as he had a young family, so the taxpayer had the additional expense of guarding his own London home as well as maintaining the official London residence.
Before anyone picks me up on this, I do realise Jacqui Smith was Home Secretary and therefore may not have been meeting with foreign officials and dignitaries, more Home officials and dignitaries? Where?
I am not taking political sides, just trying to point out some facts. If people want to suggest ways of saving the taxpayer some money on MPs' expenses how about doing away with the huge country residences for ministers of state?
If any one who objects to this were to be offered a job with a rather nice 3 bedroomed flat in a prime location offered as part of the job would they turn it down on the grounds that it is funded by the taxpayer? I thought not. Oh, one or two if you on principle? Really? 
The editor of the Daily Mirror should be ashamed at allowing such a sloppy piece of journalism to be published. It is incorrect factually, stastically and politically.
