The lawyer, who is best known for challenging Theresa May’s government on the withdrawal process from the EU, also claimed there was a link between Brexit, US president Donald Trump and extreme WW1-era populism. She told German news website Zeit: “Britain was just too arrogant and totally underestimated the EU. “The British side has long believed that the Europeans will eventually respond to their demands and ultimately yield. This misjudgment takes its revenge now.”
The 53-year-old successfully led the legal case against the UK Government following the referendum, arguing that it could not invoke Article 50 – which starts the formal Brexit process – without Parliament’s approval.
After three High Court judges ruled Parliament must hold a vote, the Government appealed but this was rejected by the Supreme Court.
The mother-of-three also called Brexit a “burden” and an “act of self-destruction” and linked it to Mr Trump.
She said: “One can not see Brexit detached from Trump, from the shift to the right in politics in Europe, from right-wing populism.
“We had that almost 100 years ago. We know how it ended.”
Her statement is likely to get under the skin of Brexiteers who in the past have accused staunch Remainer Mrs Miller of trying to block Brexit.
The entrepreneur also said Labour could not be considered a serious opposition and questioned why she was the one to take the Government to court, rather than Jeremy Corbyn’s party.
When the interviewer suggested British people can often be accused of not knowing exactly what they want, she said “that’s right” and went on to call out “many” British politicians who have not made any effort to understand Brexit’s negotiating points.
Mrs Miller appeared on the Andrew Marr Show on Sunday suggesting there is an increased support for a second Brexit referendum.
But she was quickly shut down by former Labour MP Gisela Stuart who reminded her that recent polls did not show support for this has shot up.
