Gordon Brown has appealed for discipline in his party amid fresh criticism of his leadership following Labour's humiliating by-election defeat in Norwich North.
The Prime Minister used a newspaper interview to insist there is work to be done over the summer, as MPs and ministers headed off for their summer break.
He told the Sunday Mirror: "We've got to show that we are a disciplined party getting on with the work of government. I think people are very clear that we've got a task ahead. We've got work to do to prepare for the autumn."
The PM said he is determined to spend plenty of time with his children during his break from Westminster.
But he also stressed that he would remain focused on the country, currently facing the challenges of swine flu and recession.
"My attention is focused on what I can do for the country. I will not be diverted," he said.
His comments come amid renewed concerns about his leadership among Labour backbenchers, who said he has until the party conference season in September to demonstrate he is up to the job.
The Tories overturned a Labour majority of more than 5,000 in Norwich North on Thursday to win by 7,348 votes.
A repeat of the 16.4% swing in a general election would install David Cameron in Number 10 with a majority of more than 200 seats in the Commons.
Senior Labour backbencher Barry Sheerman said Labour needs to get its "act together" and stop blaming its difficulties on the MPs' expenses scandal and also accused Mr Brown of failing to connect with voters, adding: "People don't want to know about what we've done, they want to know what we're going to do and whether we've got the leadership and the forward-vision thinking to do it."
