Nick Clegg has accused his Tory partners of letting "ideology" get in the way of education, but insists the coalition is not in crisis.
Nick Clegg believes that his party's place is in government and coalitions should be a permanent fixture in British politics.
Nick Clegg is a good speaker - possibly the best of the current crop - but I am not sure his conference address was his finest hour.
A Downing Street spokesman said earlier that the Lib Dem schools minister David Laws said last week that he was "100% behind the coalition's free schools policy".
Jeremy Browne, a former Lib Dem minister, told the BBC's Sunday Politics today that the vast majority of free schools had done “an absolutely fantastic job”.
He added that he was concerned that the Liberal Democrats risked looking like a "pale imitation of the Labour Party".
"Criticising parts of the Coalition’s work will make it impossible for the Lib Dems to claim credit for Government successes," he added.
Conservative Education Minister Elizabeth Truss has said she is "slightly surprised" by Deputy Prime Minister Nick Clegg's comments on free schools.
She told ITV News she thinks there is a "divergence of views" within the Liberal Democrat party, and that Clegg may have spoken out to "placate" elements within the party.
Nick Clegg has said that his stance on education is not a "surprise" and said that is not "a coalition crisis."
Speaking to Sky News the Deputy Prime Minister said: "It's not some great coalition crisis as it's been described, it's just a perfectly sincere difference of opinion.
"And it's about as we move to giving schools more autonomy do we at the same time ask them to respect some basic quality standards so that parents can be reassured that their children are going to be taught by qualified teachers, are going to be taught the national curriculum.
"Of course there are tensions and pinch points, we're not identical parties. No-one should be surprised about this and it's not a political crisis when some of those differences are articulated in public."
The new shadow education secretary has said he is "delighted" that the Deputy Prime Minister has called for qualified teachers in all schools, causing potential divisions in the coalition.
According to the Observer, Tristam Hunt said: "I'm delighted Nick Clegg has realised the dangers of an ideologically driven schools policy. We would be happy to work with him to reintroduce accountability, proper standards and qualified teachers in all our schools across the country."
The Deputy Prime Minister will open dividing lines with the Conservatives by insisting some education policies should not continue. Nick Clegg is due to make a speech this week over coalition's stance on education. He is due to say:
It shouldn't surprise you if I say that, although we work well with the Conservatives, our two parties still have differences of opinion, some strongly held.
Looking to the future, there are aspects of schools policy currently affected by the priorities of the Conservative Party which I would not want to see continue.
Parents don't want ideology to get in the way of their children's education.
Nick Clegg will dramatically disown key "ideological" planks of the coalition's education policy in a speech this week.
The Deputy Prime Minister is to open dividing lines with the Tories by insisting all teachers should be qualified, and the national curriculum should be taught in every school.
"It is Lib Dem policy to give all schools, whether they are academies or not, those same freedoms to attract and reward excellent teaching, set their own term dates and vary their school day," the Liberal Democrat leader will say.
One of Nick Clegg's most stalwart supporters has warned that the party is in danger of being dragged from the centre by the Liberal Democrat “shopping trolley that defaults to the left."
In his first interview since being sacked in last week’s reshuffle, Jeremy Browne told the Times said he was shocked to receive call from the leader ending his time at the home Office.
Comparing his party to a shopping trolley that “left to its own devices defaults to the left and to being the party of protest”, he says that he became exposed after years of trying to exert “corrective pressure”.
Cannabis and some "club drugs" could be legalised in a Home Office shake-up of drugs policy proposed by Liberal Democrat ministers, according to the Sunday Times (£).
The recommendations are expected to set off a bitter coalition row, with Home Secretary Theresa May resisting any significant changes.
A review ordered by Nick Clegg, the deputy prime minister, and due to be published before Christmas, is expected to suggest Britain could benefit from emulating two American states where the use of recreational cannabis is legal.
There is a "continuing argument" raging in the Coalition Government over the merits of investing in a low-carbon economy, according to Business Secretary Vince Cable.
He told BBC Radio 4's Today programme: "It is a continuing argument in the coalition, because Liberal Democrats have been arguing that we need to maintain a long-term priority towards a less carbon-based and polluting economy, and we have to make the decisions associated with that."
Former Liberal Democrat leader Sir Menzies Campbell will stand down from Parliament at the 2015 General Election.
Sir Menzies, know as "Ming" at Westminster, said he had written to Deputy Prime Minister Nick Clegg to inform him of the decision.
He was the leader of the Lib Dems from 2006-07 and served as MP for North East Fife since 1987.
Sir Menzies said: "It's been an enormous privilege to have been an MP for 26 years and to represent such a wonderful constituency as North East Fife. My wife and I have made many friends and have been supported by constituents of all political persuasions and none.
"It is always a regret to begin the process of retiring from the House of Commons but I believe now is the time to start. I have written to Nick Clegg, leader of the Liberal Democrats, and to Harry Wills, chairman of the North East Fife constituency party."
