Jeremy Hunt has called allegations that he misled parliament "disgraceful."
In a scrappy exchange, Labour MP Chris Bryant then accused Mr Hunt of lying to parliament.
Tory MP Jacob Rees-Mogg then accused the Labour front bench of being "sanctimonious hypocritical humbugs."
Conservative MP Douglas Carswell objects to the amount of time at PMQs given to debating Jeremy Hunt's position:
In a heated Prime Minister's Questions, Ed Miliband asked why David Cameron had called in Sir Alex to investigate Tory chairman Baroness Warsi but not Jeremy Hunt.
The Prime Minister said: "There is a very significant difference between the two cases.
"In the case of Baroness Warsi there hasn't been a judge-led inquiry with witnesses, taking evidence under oath, to get to all of the factual evidence behind her case.
"That is why I asked Sir Alex Allan to look at that case and establish some of the facts of that case."
But Mr Miliband said it was not the job of the Leveson Inquiry to investigate alleged breaches of the ministerial code.
Asked for Mr Cameron's response to the Lib Dem decision to abstain, a Downing Street spokeswoman said:
Asked whether the PM would attend today's debate, the spokeswoman responded: "He has got engagements in his diary. I don't know whether he will be voting."
Conservative Housing Minister Grant Shapps said the Liberal Democrats decision to abstain in today's vote on Jeremy Hunt was a "reminder that we have different perspectives on things".
"It's a reminder that this is two parties that have come together in the national interest to sort out these huge debt problems," he told BBC Radio 4's Today programme.
He added that the coalition was dealing with the "really big things", saying: "The important thing is that we continue to focus on the big picture, on avoiding getting into the situation of Spain or Greece."
Liberal Democrat MP Don Foster said Labour's decision to force a vote on whether to refer Jeremy Hunt to the independent adviser on ministerial interests over his role in News Corp's BSkyB takeover bid is a "stunt".
