The Independent Parliamentary Standards Authority (IPSA) is the body created by Parliament to independently oversee and regulate MPs’ expenses.
IPSA was created in 2009 by the Parliamentary Standards Act. New rules governing MPs’ expenses were introduced on 7 May 2010, immediately following the election by the Constitutional Reform and Governance Act. IPSA has two main roles: we regulate the expenses system and we administer and pay MPs’ expenses and their salaries.
Parliament subsequently passed legislation creating a Compliance Officer for IPSA and giving us responsibility for determining MPs’ pay and pensions.URL: http://parliamentarystandards.org.uk
