David Cameron has signalled that more coalition arguments will be played out in public as the alliance nears its first anniversary.
The Prime Minister said relations would be more "businesslike" in the wake of tensions over the AV referendum, and people would be shown more of what the Government looked like from "inside".
But he insisted that increasing "noise" from Tories and Liberal Democrats would not split the partnership before 2015.
Speaking in a round of media interviews, Mr Cameron said: "Of course coalitions are different and it does mean sometimes quite noisy arguments between Conservatives and Lib Dems, because we are different parties and we don't always agree."
He added: "I think maybe what we need to do is see more of what the Government is like from the inside."
Mr Cameron said the coalition had made "good progress", taking "long-term decisions" for the good of the country.
"We have proved, I think, that a coalition Government can be a strong government and a determined government rather than just a lowest common denominator government," he said. "You are going to have noises from, frankly, both parties. We have had that for the past year, we will have that in the future."
The PM repeatedly refused to say he was "friends" with his Lib Dem deputy Nick Clegg.
But he stressed that the two men - who memorably sealed their deal with a joint press conference in the Downing Street rose garden last May - worked well together and "shared a common endeavour". "We get on well together," he said. "In any organisation you've got to have good people, you've got to have good ministers, but you have got to be able to get on together."
Meanwhile, public confidence in the coalition Government is at a record low, according to a poll released on the eve of its first anniversary. The ComRes survey for ITV News found that almost half (49%) of voters think the coalition has been bad for Britain and more than half (53%) think its record so far has been disappointing. Fewer than one in three (28%) expected it to run a full five years, as Mr Cameron and Mr Clegg say it will.
