Boris Johnson is facing a possible investigation into breaches of the Conservative Party code of conduct.
The party has received dozens of complaints about the ex-foreign secretary’s comments about Muslim women wearing burkas.
The complaints will be looked at by an independent panel which could refer Mr Johnson to the party’s board, which has the power to expel him.
The party declined to comment on the details of the investigation.
A Conservative Party spokesman said: “The code of conduct process is strictly confidential.” A source close to Mr Johnson offered no comment.
Mr Johnson has rejected calls to apologise for saying people wearing burkas looked like “letter boxes” or “bank robbers”, in a Daily Telegraph column in which he also argued against a ban on full-face veils.
Critics have accused him of stoking Islamophobia to boost his Tory leadership ambitions but his supporters have said he was speaking up for “liberal values”.
It comes as a watchdog which advises ex-ministers on taking new jobs ruled that Mr Johnson broke ministerial rules by taking up his weekly column at the Telegraph without consulting it first.
The Conservative Party has been accused of not doing enough to tackle anti-Muslim prejudice in its ranks, despite an initiative to boost tolerance and diversity.
The party’s code of conduct states that Tory officials and elected representatives must “lead by example to encourage and foster respect and tolerance” and not “use their position to bully, abuse, victimise, harass or unlawfully discriminate against others”.
The independent panel will decide whether to refer Mr Johnson to the party’s board. Possible action includes suspension of membership or expulsion from the party among other, lesser sanctions.
Conservative Party chairman Brandon Lewis and leader Theresa May have both called on Mr Johnson to apologise for his comments.
The founder of the Conservative Muslim Forum, Lord Sheikh, has written to Mr Lewis demanding “serious action”, while former attorney general Dominic Grieve said he would quit the party if Mr Johnson became prime minister.
A hundred Muslim women who wear the niqab or burka have signed a letter to Mr Lewis, calling on him to withdraw the Conservative whip from Mr Johnson and launch an independent inquiry into Islamophobia in the party.
“We are not forced to make these clothing choices, nor are we oppressed,” the women write in their letter, which has been issued to the media by the Muslim Council of Britain.
They say Mr Johnson’s words will “inflame tensions in a way that makes it easier for bigots to justify hate crimes against us”.
