Dickens
I think he's stated something along the lines that he may have "accidentally" opened a porn video. 
Why are MPs scrolling through their iPhones anyway when they're in the House?
Like others, I feel sorry for his wife, but her comment, "that if women were "mad" with every man who watched porn "you would not have many wives in the world". has lessened my sympathy somewhat. Entirely missing the point.
... and not all porn is harmless either. Does she, or the men who watch, know that it's an industry into which women are frequently trafficked? And that some men have admitted that their addiction to it has led to them being unable to hold down normal relationships with their wives and girlfriends?
He just should not have been watching it at work, it's as simple as that.
This seems to have been suggested by the person who interviewed him. It was on the news last night and the interviewer said,’Was it an accident?’ When Parish wouldn't comment and said he would wait for the result of the inquiry the interviewer said, ‘I meant did you open it by accident?’ Which is when Parish seemed to cotton on to the idea then said that he did. I thought at the time that the interviewer had given him an idea of what line to take and that the interviewer was at fault.
