Heather Rose Brooke is a British-American journalist and freedom of information campaigner. Resident since the 1990s in the UK, she helped to expose the 2009 expenses scandal, which culminated in the resignation of Speaker of the House of Commons Michael Martin, dozens of MPs standing down in the 2010 general election and multiple MPs being jailed.

The United Kingdom parliamentary expenses scandal was a major political scandal that emerged in 2009, concerning expense claims made by members of the British Parliament in both the House of Commons and the House of Lords over the previous years. The disclosure of widespread misuse of allowances and expenses permitted to members of Parliament (MPs) aroused widespread anger among the UK public and resulted in a large number of resignations, sackings, de-selections and retirement announcements together with public apologies and the repayment of expenses. Several members, and former members, of both the House of Commons and the House of Lords were prosecuted and sentenced to terms of imprisonment.
