Gina Miller, the businesswoman who took one of the cases that led to the Supreme Court ruling the government's prorogation of parliament was unlawful, said she was subjected to 'disturbing' verbal abuse while walking with her daughter.

Miller said she was recognised on the street as she took her 12-year-old daughter for an eye test on the day after the court ruling last week.

"People were stopping in their cars and rolling their windows down and calling me 'traitor' and saying, 'There's a lamppost over there'," she told The Times in an interview.

"And you just think, it's extraordinary. You know, I'm with my child and that's disturbing."

Miller said her children have known her as a campaigner all their lives and that she tells them: "This is why mummy is fighting."

Miller told the newspaper that her teenagers have come across messages disparaging her on social media.

"I get sent letters saying my children are mongrels. I have to make sure that they are not seeing all of this, but I explained to them, 'We have to just be who we are, and if we reply with anger all we do is stoke those fires.'

"I much prefer to stay calm and try and explain to people and talk, but it's a hard thing to do," she told the newspaper.
