Gina Nadira Miller (born 19 April 1965) is a Guyanese-British business owner and activist who initiated the 2016 R (Miller) v Secretary of State for Exiting the European Union court case against the British government over its authority to implement Brexit without approval from Parliament. In September 2019 she successfully challenged the government's prorogation of Parliament, formally supported in the legal case by the former prime minister Sir John Major and the shadow attorney general, Shami Chakrabarti. She founded the True and Fair Campaign in 2012, calling for an end to financial misconduct in the investment and pension industries. She also founded the True and Fair Foundation.
“The precedent Mr Johnson will set - if this is allowed to stand - is terrifying: any prime minister trying to push through a policy that is unpopular in the House and in the country at large would from now on simply be able to resort to prorogation.”
