who decides pay and allowances of ministers in the state
Salaries of Members of the United Kingdom Parliament In 2010, the payment of MPs' salaries and allowances, and many staff, was moved from the Fees Office, which was effectively self-policing by MPs of their expenses, to a more autonomous body, the Independent Parliamentary Standards Authority.[20] In 2010 the IPSA was also given the responsibility of setting MPs' salary levels. It is accountable to the Speaker's Committee for the IPSA, comprising the Speaker, the Leader of the House, the Chair of the Standards and Privileges Committee and five MPs selected by the Speaker (one of whom is the Shadow Leader of the House).
