Tory MP Nigel Mills was supposed to be listening to a pensions expert give evidence in a Parliament hearing, but he was instead caught playing Candy Crush on his iPad during the meeting of the Commons Work and Pensions Committee.
Spotted closely studying his Apple tablet, he was seen swiping the screen with his finger as he did his best to complete levels of the popular game.
Now he has admitted to having a "game of two" during a section of the meeting which he "wasn't focussing on". Maintaining that he still takes his job "very seriously" he has said he will "try not to do it in future".
TaxPayers' Alliance's Andy Silvester is not happy, and stated: "Taxpayers don't put representatives in Parliament to mess around on video games."
Speaking to The Sun, Mr Mills explained: "It was a long meeting on pension reforms which is an important issue that I take very seriously.
"There was a bit of the meeting that I wasn't focussing on and I probably had a game or two.
"I should not do it but if you check the meeting, I would say I was fully engaged in asking questions I felt were particularly important on how we get pensions issues right. I shall try not to do it in future."
Mr Mills is one of 90 MPs that received a free iPad device ot help them with their work.
Candy Crush Saga is available to play as an app on mobile phones and tablets, or on Facebook, and has become extremely popular with more than 700 million games played on mobile devices alone.
According to ThinkGaming, the app makes an estimated £400,000 a day, as players purchase extra 'lives' and 'boosters' for their games.
After being elected as the MP for Amber Valley, Derbyshire back in 2010, he took the victory with a majority of just 536.
