Cameron was about to go on vacation -- one that ended up being cut short -- when people voiced their concern over tensions in Iraq and the government.
"Wherever I am in the world I am always within a few feet of a BlackBerry and an ability to manage things should they need to be managed," said Cameron. "And indeed as I have done on I think almost every holiday that I have enjoyed over the last few years."
His critics weren't satisfied. Labour MP John Mann said the prime minister's flippant attitude was a sign of his inability to lead.
"Government by BlackBerry is not any kind of Government," he said.
Obama also has been criticized for his vacations. He has been in Martha's Vineyard for the greater part of the past two weeks. After speaking on the beheading of American journalist James Foley, pictures of the president golfing were splashed across media outlets, causing his critics to lash out.
