Portraits of MPs have cost the taxpayer around £250,000, a Freedom of Information (FOI) request has revealed.
A painting of Work and Pensions Secretary Iain Duncan Smith cost £10,000 while Labour MP Diane Abbott sat for a portrait charged at £11,750.
The figures came to light after an investigation by the Evening Standard newspaper.
Backbencher Dennis Skinner defended his decision to sit for a portrait, saying that it helped an out of work artist "get some work."
The artworks were commissioned by the cross-party Speaker's Advisory Committee on Works of Art - chaired now by Labour MP Frank Doran - since 1995.
A Commons spokesman told the Standard:
- More of the portraits are freely available to view on the Parliament website
