Gina Miller, who famously took the Government to the Supreme Court over the Brexit Bill, has pledged to become a nuisance to Brexiteers.
She told talkRadio Brexiteer MPs have not heard the last of her, as she promised to be active in negotiations to leave the European Union.
In an interview with the Badass Woman's Hour evening programme, the anti-Brexit activist described herself as a "superwoman" who would stop at nothing to disrupt Brexit.

Mrs Miller called on people up and down the country to "keep an eye" on the Government as they take Britain out of the European Union.
The activist told the show's host that she was humble, but then added that she saw herself as someone who could save the world.
She said: "I have always been a troublemaker. I always saw myself as Superwoman, someone who could save the world!"

The woman who has led the fight against Brexit has always seen herself as superwoman
The pro-European activist described the Brexit negotiation process as unpicking an intricate tapestry bit by bit after 44 years of careful work.
She revealed that she feels “disappointment, regret about the way the whole Brexit campaign was fought and nervousness about what’s going to happen" when Article 50 is triggered.
Mrs Miller added: "I’m really worried about just letting the Government get on with it because they don’t have the time, the skills, or a plan.
"I will not let them just get on with it. The MPs have no backbone, I fought really hard for them and they voted against themselves."
