In the UK, a Tory MP has apologised "unreservedly" for playing games on his iPad during a select committee hearing, as the Commons authorities launched a mole hunt for whoever caught him on camera.
Photographs published by The Sun showed Nigel Mills enjoying the online game Candy Crush Saga and he says "it will not happen again".
A Commons spokesman says the photos, shot over Mr Mills' shoulder, broke strict parliamentary rules.
He has tweeted to apologise for his behaviour.
"I guarantee it will not happen again. It is a fantastic privilege to represent Amber Valley, and I hope constituents will continue to support my campaigns such as lower taxes for hard-working people," he wrote.
I apologise unreservedly for my behaviour at the committee meeting and realise it fell short of what is expected of a Member of Parliament.

The House of Commons authorities have launched an investigation into how the footage was obtained.
A spokesman said: "This was a breach of the filming rules for House of Commons Committee Rooms, and will be investigated by the Serjeant at Arms."
The decision to investigate the witness who made the film rather than the MP sparked some criticism on social media.
The Sun quoted a source at the meeting who claimed Mr Mills played the game for around two-and-a-half hours on an iPad allegedly funded by the taxpayer.
Mr Mills told The Sun: "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 focusing on and I probably had a game or two."
"I shouldn't do it but if you check the meeting I would say I was fully engaged in asking questions that I thought were particularly important in how we get the pensions issue right. I shall try not to do it in the future."
British Prime Minister David Cameron said Mr Mills would be "embarrassed" by what had happened.
Speaking in south London, Mr Cameron said: "I haven't spoken to Nigel about it. I know he is a very hard-working MP, I know him well, he fights very hard in his constituency for people in Derbyshire, he works very hard in Parliament."
"I'm sure he will be embarrassed by what he saw in the papers today and he will work even harder in the future."
The committee met last Monday and was discussing pensions and the insurance industry ahead of an Autumn statement by the British chancellor.
Candy Crush Saga is a free to download mobile game where users pay extra for more moves to improve their score.
