Two Birmingham and Black Country MPs continue to employ a member of their family despite the practice being banned for new members of Parliament.
Valerie Vaz, MP for Walsall South, employs her husband, Paul Townsend, as a senior parliamentary assistant.
Jess Phillips, MP for Birmingham Yardley, employs her husband, Tom Phillips, as a constituency support manager.
James Morris, MP for Halesowen and Rowley Regis, also employed his wife, Anna Mellitt, as a communications officer until October 2016.
Voters must be able to have confidence that our democracy is resourced in an open and transparent way, so it's welcome that Parliamentary authorities have taken steps to reform the system."
Of the 589 returning MPs, 122 have declared the employment of a relative in the latest Register of Members' Financial Interests. None of the 61 new MPs who secured their seats at the general election on 8 June are allowed to do so.
Campaigners say there needs to be a clear end date for all MPs.
