David Cameron (R) and Nick Clegg
David Cameron and Nick Clegg have set out initiatives to mark the halfway point in their government.
Cameron promised more help on childcare costs, help towards care costs for the elderly and investment in roads and high speed rail.
The PM insisted the coalition was a "serious five-year commitment" to give Britain "strong, stable and determined leadership".
Labour have dismissed the review as "another relaunch".
Nick Clegg said the coalition had brought about "big, bold reforms" that would stand the test of time.
Described by Downing Street as a "stock take", the mid-term review also looks at how successful the government has been in meeting its coalition agreement promises and commits them to further reforms.
The full document was presented to the cabinet for the first time on Monday morning.
"We are dealing with the deficit, rebuilding the economy, reforming welfare and education and supporting hard-working families through tough times. And on all of these key aims, our parties, after 32 months of coalition, remain steadfast and united," Cameron and Clegg write in a joint foreword to the review.
"Of course there have been some issues on which we have not seen eye to eye, and no doubt there will be more. That is the nature of coalition.
"But on the things that matter most - the big structural reforms needed to secure our country's long-term future - our resolve and sense of shared purpose have, if anything, grown over time."
The review pledges to help families with their childcare costs and to "provide dignity in old age" with an improved state pension and help towards the cost of long term care.
This follows a review by economist Andrew Dilnot, which recommended setting a care bill limit of between £25,000 and £50,000 to stop pensioners being forced to sell their homes to cover costs but the government has looked at a number of options, including a £75,000 limit.
Shadow health secretary Andy Burnham said a cap of £75,000 would mean the coalition had "fallen far short" of finding a fair solution.
Cameron and Clegg's joint foreword states: "We will support working families with their childcare costs. We will build more houses and make the dream of home ownership a reality for more people.
"We will set out plans for long-term investment in Britain's transport infrastructure.
"We will set out two big reforms to provide dignity in old age: an improved state pension that rewards saving, and more help with the costs of long-term care.
"And as we take these steps to reshape the British state for the 21st century, we will take further steps to limit its scope and extend our freedoms. We will be making announcements about each of these policy initiatives in due course.
"Our mission is clear: to get Britain living within its means and earning its way in the world once again."
