Democratic Unionist MP Peter Robinson, and his wife Iris, were both named on a list of more than 100 politicians who employ family members.

But the couple were also among just five MPs who have given jobs to more than one family member.

Mrs Robinson employs their son, Jonathan Robinson, as an office manager, and daughter-in-law Ellen Robinson as a part-time secretary.

Mr Robinson employs his daughter, Rebekah Robinson, as "office manager and private secretary" and their other son, Gareth Robinson, as parliamentary assistant.

Former Northern Ireland Secretary Peter Hain was also named as an MP employing a relative.

The list featured the head of the House of Commons anti-sleaze committee and one of the MPs in charge of reviewing the expenses regime.

It included three ministers, Home Secretary Jacqui Smith, Environment Secretary Hilary Benn and Housing Minister Caroline Flint.

The disclosure of 106 MPs who employ relatives follows MP Derek Conway's suspension from the Commons over payments to his son.

There is no suggestion that those who have volunteered the information so far have broken the rules.
