She said: “I will be calling for the Government to close British Islamic faith schools.

“That doesn’t mean I am picking on British Islam, but if you think about what our security services are looking at - 2,000 individuals that have come from those faith schools - when does indoctrination start?”

She went on: “If the same thing was coming from Christian schools or Jewish schools we would take the same approach but we have to understand radicalisation is coming from somewhere.”

The former Ukip director also unveiled plans to end "foreign abuse" of the NHS and to get tough on crime.

As for the future of her party, she said she wanted a "grassroots revolution" which will see her "march Ukip into Westminster".
