Reform UK MP Lee Anderson has refused to apologise to Sadiq Khan and lamented the London Mayor for his record in City Hall.
Anderson, who lost the Tory whip after claiming Khan gave the capital away to "Islamists", doubled-down on his comments at Reform UK's annual conference at the NEC in Birmingham.
Speaking to 4,000 Reform UK members, the Ashfield MP said: "In my opinion, he has given our capital city away and he should be thoroughly ashamed of himself.
"I was told at the time that I must apologise to Labour's Mayor in London.
Lee Anderson stood his ground
GBN"Now, let me tell you in our conference I will never apologise to that man."
He added: "Let's look at his track record. Overall crime up by 21 per cent. Violent crime 35 per cent. Homicides five per cent. Knife crime 54 per cent. Sexual offences 51 per cent.
"It should be him apologising to the people of London."
Anderson's appearance at the NEC sparked a number of notable moments, including his decision to rip up a BBC licence fee letter.
The 57-year-old was met by a chorus of chants calling for him to "tear it up" after asking the 4,000-strong crowd what to do with the letter.
However, Anderson's comments about Khan come after much fury between the pair.
The Ashfield MP, who returned on July 4 as one of Reform UK's "famous five", was forced out of the Tory Party after previously serving as deputy chairman.
In his attack against Khan, Anderson called for the London Mayor to be ousted from office.
He said: "How does he think the 10 million people who live in London feel under his leadership? This man needs booting out of office for the sake of London.”
However, Khan won his third successive election earlier this year to return to City Hall for another term.
Khan received 43.8 per cent of the vote, with Conservative challenger Susan Hall trailing in second on 32.7 per cent.
Reform UK's Howard Cox finished in a distant fifth place, with the populist party failing to retain its deposit on just 3.1 per cent.
