This petition was rejected

The Government e-Petitions Team gave the following reason:

The Government and Parliament don’t have the power to set MPs’ pay. That power was given by Parliament to the Independent Parliamentary Standards Authority (IPSA) in 2010, so that after 2012 MPs no longer had control over their own pay. IPSA conducted a public consultation after 2012 and decided what the salaries of MPs should be after the election.

If you would like to contact IPSA about its decision, here’s how to contact them:

The only way that the decision of IPSA could be challenged would be if the law was changed to return the power to set MPs’ pay to the MPs themselves, or to give the power to some other body. The law could only be changed by Parliament.
