Former Conservative Party deputy chair Lee Anderson has joined his third new party since 2018 as the Ashfield MP becomes Reform UK's first member of parliament.
The 57-year-old quit his role with the Conservatives in January to rebel against Rishi Sunak's Rwanda bill.
The MP has been notoriously outspoken on a number of issues since being elected to the Commons in 2019, none more so than islamophobia.
He told GB News "islamists" had "got control" of the Mayor of London, Sadiq Khan.
"He's actually given our capital city away to his mates," he added.
Tory MPs refused to say whether Mr Anderson's comments were islamophobic in days that followed, nonetheless he was later suspended from the Conservative Party for them.
The former Labour councillor has now joined Reform UK, who have been consistently polling well this year.
Introduced at a press conference as "no nonsense, no waffle" by party leader Richard Tice, Mr Anderson said several times: "I want my country back".
He added: "My opinions are not controversial. My opinions are shared by millions of people around the country.
"I feel we are slowly giving our country away. We are erasing our way of life … we are allowing people into our country who will never adopt our values."
A Conservative spokesperson said: "Lee himself said he fully accepted that the chief whip had no option but to suspend the whip in these circumstances.
"We regret he’s made this decision. Voting for Reform can’t deliver anything apart from a Keir Starmer-led Labour government."
