An MP under investigation for allegedly watching pornography in the House of Commons has claimed he may have opened it on his phone by mistake.
An inquiry has been launched after Neil Parish referred himself for investigation.
He has refused to resign as an MP or as head of the environment select committee until the inquiry concludes.
Two female colleagues complained after claiming to have seen him looking at adult content while sitting near them.
Mr Parish has been suspended from the Conservative parliamentary party, pending the outcome of the investigation by Parliament's standards commissioner Kathryn Stone.
If she finds that he has violated the code of conduct for MPs, possible punishments range from apologising to the Commons to suspension or expulsion.
Questioned by the BBC on Friday, Mr Parish said he would co-operate fully with the inquiry and would await the outcome before commenting.
"Of course it's embarrassing," he said. "And it's embarrassing for my wife and family, and so that's my main concern at the moment. I have a very supportive wife and I thank her for that."
Asked if it was a mistake, he said: "I will await the findings of the inquiry."
Pressed on whether he had opened something on his phone in error, Mr Parish said: "I did, but let the inquiry look at that."
Mr Parish also said he would resign if "found guilty" by the inquiry, saying he understood the upset he might have caused and "I apologise for that".
However,
in a statement on his website, he said he would continue working as an MP and committee chair, despite calls from female colleagues for him resign or at least to stop attending Parliament while under investigation.
On Wednesday, it emerged that a female minister had reported a male colleague for viewing pornographic material while sitting beside her in the Commons chamber. The female minister said she had also seen the MP watching pornography during a hearing of a select committee, The Times reported.
A second female Tory MP said she had tried but been unable to capture video proof of him doing so.
The allegations were subsequently revealed to have been made about Mr Parish, who said he had referred himself for investigation.
Mr Parish serves as the MP for Tiverton and Honiton in Devon and also chairs the Commons Environment, Food and Rural Affairs Committee - but the investigation does not prevent him from continuing in either role.
