An Independent Group MP criticised Theresa May for being on her phone while he asked his question.
Chris Leslie was in the midst of questioning the Prime Minister as to whether she would respect parliament if it opted for a confirmatory referendum on her deal.
But he broke off saying: "I don't want to interrupt her while she's on her phone".
There were grumbles of outrage but the a smiling Prime Minister replied: "I apologise to you - just a little bit of female multitasking trying to take place there."
Mrs May is facing a battle to hold on to power as MPs seek to seize control of parliamentary business in a bid to secure a softer Brexit , while some of her own backbenchers openly discuss her removal as Prime Minister.
She made an oral statement to MPs on the decision reached at last week's EU summit to extend the Brexit negotiation period beyond March 29.
This evening MPs will then debate and vote on a proposal to force a series of indicative votes on alternatives to her Withdrawal Agreement.
Defeat for the Government on Monday night over the plan - tabled in an amendment by former ministers Sir Oliver Letwin and Dominic Grieve and Labour MP Hilary Benn - would be a further humiliation for Mrs May.
The proposal seeks to pave the way for a series of indicative votes in the Commons on Wednesday, effectively taking control of the Brexit process out of the hands of the Government.

Sir Oliver acknowledged that any votes would be advisory rather than binding on the Government and it may take several rounds of voting before a majority is found for any of the options - if one can be found at all.
He said Mrs May "hasn't been able to get a majority and we don't know what she could get a majority for, so once we find that out there is a way forward, in principle, and then the next thing would be for the Prime Minister to take that forward and for the Government to implement it".
