Records revealing details about who MPs rent their taxpayer-funded homes from have been released, despite Commons Speaker John Bercow warning that it would cause a "security risk".
The Independent Parliamentary Standards Authority (Ipsa) published a list of the landlords and agents of the 320 MPs claiming rental expenses last month..
The list shows a number of MPs that rent properties do so from fellow MPs or peers.
They include Labour MP Jessica Morden, who rents from Bridgend MP Madeleine Moon, while Conservative Keith Simpson rents from Lord Flight.
Last month many MPs argued in the Commons that it could be used maliciously.
Mr Bercow wrote to Ipsa claiming there was a "very real danger" that residential addresses could be discovered as a result of the details being released.
Ipsa said it had withheld some details from the records published today where an MP or landlord had shown the information could lead to their address being identified.
The expense claims were uncovered in an investigation by Channel 4's Dispatches, which is due to broadcast a film called MPs: Are They Still At It? tonight.
