British member of Parliament Boris Johnson, the former foreign secretary for Prime Minister Theresa May, is facing an investigation launched by his own Conservative Party over recent remarks he made about burqas, the BBC reported.
The party declined to comment on the disciplinary procedure.
A spokesperson the party said, "The code of conduct process is strictly confidential".
The repercussions could exasperate the party's growing civil war, where the debate over Johnson's comments has developed into a proxy war between Brexiteers and Remainers in the parliamentary party.
The former minister Anna Soubry added: "Many One Nation Tories would not stay in the Conservative Party should Boris Johnson become leader".
Furthermore, given the responses from other MPs, specifically Ms Dorries, and the broader concerns that have been raised by the Muslim Council of Britain amongst others, we believe that there must now be an independent inquiry into Islamophobia in the Party to tackle this issue once and for all.
And there was no immediate comment on the news that he faces investigation.More news: Meghan Markle’s Birthday Gifts: What She Can and Can’t Keep

Under party rules, the head of the investigation may dismiss complaints that are obviously trivial or lacking in merit and those which can not fairly be investigated.
But the MP Nadine Dorries, retorted: "The people in Westminster who are so outraged are actually terrified that at some stage any day soon Boris may make a challenge for the leadership and Number 10".
The panel will consider whether Johnson should be disciplined following a deluge of complaints against him. It says elected Tories must "lead by example to encourage and foster respect and tolerance" and act "in a manner which upholds the reputation and values" of the party.
The panel reports its findings to the party chairman but the final decision on an appropriate sanction could go to May as leader or to the party's board.
But the survey for the Sky News found people are split as to whether the former foreign secretary should apologise for his remarks - 45 per cent think he should do so, 48 per cent think he should not. "Or perhaps her deliberate attempt to sabotage the Brexit negotiations".
However, there has also been a groundswell of support including from prominent backbenchers as Jacob Rees-Mogg.
He told LBC on Wednesday: "No, she's clearly wrong to have asked him to apologise".
