It is not often that a UK citizen decides to sue their government, but that is exactly what former lawyer and fund manager Gina Miller is doing. After already shaking up the investment scene with her company SCM and the True and Fair Foundation, both of which seek to combat hidden charges in the industry, she is now taking on the legal process surrounding Article 50. In a High Court lawsuit set to begin on October 13, she will argue that it would be illegal to set the process of leaving the EU into motion by the prime minister’s royal prerogative rather than through a Parliamentary vote. With just a few more days to go before the case's starting shot, Gina talks to Jen about why this is not about stopping Brexit but about getting legal certainty and why Nick Clegg and Ed Miliband's recent call for a Parliamentary vote has muddied her case.
