We are pleased to see that Witney MP David Cameron is happy for details of his expenses for a second home to be released.

It is disgraceful that the House of Commons is disputing a ruling by a Freedom of Information tribunal that the expenses of MPs for second homes should be placed in the public domain.

This is public money received by MPs in the pursuit of their public duty.

We do not dispute that MPs should receive fair expenses for doing their job. For most that means having to run two homes.

However, the system has to be transparent. Only then can MPs counter suspicions of the public that they are on something of a gravy train.
