The acting shadow work and pensions secretary, Stephen Timms, has accused Labour MPs who voted against the government's welfare bill of "undermining" the party's efforts to win back power.

He also expressed his concern that a number of new MPs joined veteran rebels like Dennis Skinner and Jeremy Corbyn in defying the whip .

Mr Timms told BBC London 94.9:

"I think Harriet [Harman] miscalculated the amount of opposition to the welfare bill," says Labour MP and mayoral candidate Dianne Abbott.

She says it will force 300,000 children into poverty, adding: "Outside of Westminster I think Labour supporters are pretty united. This is a bad bill and we have to oppose it."

Ms Abbott insists the Conservatives do not have a mandate for the welfare cuts.

New Lib Dem leader Tim Farron has found his religious views in the spotlight in recent days with questions asked about whether they conflict with his political position.

Nick Cohen, in the Spectator,, external says no, they don't.

Next up on Today is former Labour minister David Blunkett. He says his party is "in emotional trauma" and bewildered about "where we go from here", but it must "avoid the trap" of opposing everything the government does because that makes it easy for George Osborne. 

Mr Blunkett says he meets young people regularly who "expect to make logical, rational decisions" about how many children to have and they "don't expect the state to pick the bill up". That, of course, is a reference to the plan to limit future child tax credits to the first two children.

Andy Burnham says he's "firing the starting gun on Labour's opposition" to the welfare bill, but he didn't vote against it. How come? Labour's compromise amendment said the party "declines to give a Second Reading" to the Bill. So Labour MPs who did what they were told last night - Burnham among them - voted for a Labour amendment that said they wouldn't give the bill a second reading, then abstained 15 minutes later when they got a chance to vote for real on whether to give the bill second reading. Confused? That's political compromise for you.

Burnham can fairly hint he fell out with Harriet Harman over the idea of accepting cuts and pushed her to change her position - and say he would do things differently if he got elected leader. But the comments below his Facebook posting (see our 7:39am entry) explaining all this suggest some potential supporters are unimpressed. 

One reads: "I am so sorry Andy, but tonight you lost my vote for leadership." Posts on the net are no certain judge of sentiment, but it's fair to say if George Osborne hoped to create splits, confusion and rancour in Labour's ranks, he managed.

Aside from the welfare bill, the news agenda on Monday was dominated by David Cameron's speech on tackling extremism and the papers have been giving their verdicts on it.

TheTimes welcomes the prime minister's words, external, saying his “appeal to reason is sincere. Moderates of all faiths and none should embrace it." The paper's leader column says Mr Cameron was right to speak directly to those who might be seduced by Islamic State propaganda and warn them of the realities they would face. “Strip out the jihad’s spurious claim to religion and the reluctance of some civil libertarians to see the full force of the law applied against it looks ridiculous," it adds.

TheGuardian says the prime is "right to try", external to fight the IS ideology, but he "tripped up on the details" in his speech. Its editorial says he "cannot convincingly claim that free speech is a core British value" but then vow to silence those operating within the law but whose words you don't like. 

"The other great rhetorical weakness", the paper argues, is to claim that "only the extremists divide people into good Muslims and bad ones, when the whole thrust of the government's policy is to make this distinction". 

In between writing letters to ministers asking them to save money, George Osborne will appear before the Commons Treasury Committee to be quizzed about his Budget. There'll also be Treasury Questions in the Commons itself and the second reading of the Finance Bill - the measure which puts the tax changes from the Budget into law. 

Elsewhere, there are plenty of other Commons committees sitting. Theresa May is up before the home affairs committee, Philip Hammond before the foreign affairs one. The Public Administration and Constitutional Affairs will also hear evidence about the forthcoming EU referendum, and there are many more to dip into when we can.

Moving forward to today and it's a busy one. Top of the list is the launch of the 2015 spending review. The Treasury will write to cabinet ministers today to ask for savings in their departments to total £20bn. The BBC understands specific targets will not be set for departments, but ministers will likely report back by September.

George Osborne will deliver the outcome of the review on 25 November.

BBC Newsnight's Laura Kuenssberg says the Treasury believes billions can be found from selling off public land and by devolving spending from Whitehall, under the chancellor's so-called "Northern Powerhouse" strategy,

Harriet Harman argued that voters had told Labour something at the election - that they were quite comfortable with a slightly tougher welfare system - and the party must take that on board. However, a large swathe of her MPs disagreed.

The big question now is how can a new Labour leader keep those MPs in line by leading from anywhere but the left. They've sent a message that they're quite happy to rebel on issues like this.

One man looked very cheerful in the Commons last night - George Osborne. And you can see why. We're not having a big debate this morning about £12bn of welfare cuts, we're talking about the Labour Party's internal splits. And he's is very happy about that.

The welfare bill passed despite a Labour revolt. Some 48 of its MPs defied orders from acting leader Harriet Harman to abstain and instead voted against the bill.

Those who rebelled included leadership contender Jeremy Corbyn and London mayoral candidates Sadiq Khan and David Lammy.

During a five-hour debate, Labour MP John McDonnell said he would "swim through vomit" to oppose the legislation.

Ms Harman has faced criticism for her stance, with many MPs saying she should have been more outspoken in her opposition to curbs on child tax credits and cuts to other in-work benefits.

Mr Corbyn's three Labour leadership rivals - Andy Burnham, Yvette Cooper and Liz Kendall - followed Ms Harman's lead and abstained.

Unless you were up pretty late last night you might have missed the big news from the Commons, so let us bring you up to speed. 

The government's Welfare Reform and Work Bill, external passed its first Commons hurdle, after MPs voted by 308 votes to 124 to give the Bill a second reading. The next stage of the Bill's progress will be the committee stage when MPs will debate the details in the legislation and propose amendments.

Those numbers gave the government a majority of 184 votes.

This bill contains the details of the much-talked about £12bn in welfare cuts, including limiting child tax credit to two children. 

Work and Pensions Secretary Iain Duncan Smith - above - said it would put welfare funding on a "more sustainable footing" while protecting those most in need. Read more.
