John Bercow could become the first Speaker to be denied a peerage upon his retirement because of alleged anger from ministers who believe he is biased over Brexit.
It has been tradition for more than two centuries that Speakers are automatically offered a seat in the House of Lords after completion of their duties in the Commons.
But ministers are said to have been frustrated by his behaviour amid the recent Brexit turmoil.
A Cabinet source told The Times: "It's a good job peerage nominations are in our gift.
"I'm sure we'll be thinking carefully about which individuals we would choose to elevate to the House of Lords.
"I can't imagine we would look favourably on those who've cheated centuries of procedure."
The Speaker came under fire from Tory ministers for approving a vote on the so-called Grieve amendment last week. They accused him of tearing up years of precedent by allowing MPs to control business of the house and letting them vote on amendments to Theresa May's Meaningful Vote motion.
Critics said allowing MPs to vote on an amendment which the Government had not approved and reduced the time it had to present a Brexit Plan B if Mrs May’s original deal failed broke years of Parliamentary precedent.
However, he denied this and said he made an “honest judgement”.
He was embroiled in further Commons clashes with ministers as he accused the Government of blocking proposals to allow MPs on baby leave to vote by proxy.
The Speaker said there had been a "lamentable failure of leadership" to introduce changes allowing a colleague to register a vote on behalf of an MP absent on maternity or paternity leave. It came after Labour's Tulip Siddiq revealed she would postpone her caesarean for the Brexit vote.
He has also been accused of bias on Brexit after revealing he voted remain during the 2016 referendum. Mr Bercow has also faced accusations of bullying which he has always strenuously denied.
Mr Bercow has been the Commons speaker since June 2009. He is expected to stand down this summer after saying he wanted to stay on to see through Brexit.

Usually Speakers have stood down from their roles as MPs at the same time which triggers a by-election over their seat, Mr Bercow’s being that of Buckingham.
The Queen is then usually asked in a motion in the Commons to give them a peerage.
Despite some notorious bust-ups in his time, he has relished the role and in a 2011 interview said: "If you asked me if I'd rather be Speaker or a very senior minister, I'd say Speaker.”
