It's been a long, hot day and we are signing off for now. There is plenty to look forward to tomorrow with Labour's four leadership contenders, as well as Harriet Harman and Greg Clark, addressing the Local Government Association conference. Theresa May is off to Paris to discuss the situation at Calais while there is also a busy day in Parliament, with a debate on Britain in the world and an adjournment debate on the future of a Doncaster coal mine tabled by Ed Miliband - remember him? Join us for all that.

Lord Blair, the Commissioner of the Metropolitan Police at the time of the 7/7 bombings in 2005 has cautioned against taking a tougher line on religious fundamentalism and said he doesn't expect the West to overcome the threat of Islamic extremism in his lifetime. 

Speaking to the BBC's Newsnight in advance of the ten year anniversary of the London attacks, he raised concerns about David Cameron's recent call for less tolerance of intolerance. 

Lord Blair denied he was criticising the government's approach but cautioned, "I just think we have to be incredibly careful, we shouldn't be doing this to the community, we should be doing this with the community."  

He added:

We reported earlier that Iain Duncan Smith was among nearly 20 MPs to have had the credit cards they use to pay their expenses suspended. The Press Association said this was due to concerns over debts being wracked up. But the Independent Parliamentary Standards Authority has now made clear that the cabinet minister's card was deactivated by mistake and no money was outstanding. A spokesman for Mr Duncan Smith said:

The next stage in the parliamentary debate on plans to give 30 hours of free childcare to children in England will take place later than expected after two influential committees in the Lords criticised the legislation. The Delegated Powers and Regulatory Reform Committee complained that the Childcare Bill was flawed, vague and lacking in substance. Another group of peers, the Constitution Committee, had already complained about a tendency by the government to introduce vaguely worded legislation that left "much to the discretion of ministers". The committee said the Childcare Bill was a "particularly egregious example of this development". This evening, Education Minister Lord Nash, announced that the report stage of the Bill - when peers will debate and vote on amendments to the legislation - would take place in October. The Labour leader in the Upper House, Lady Smith, said the government's handling of the measure had serious implications for the House of Lords as a revising chamber.

Our colleagues on Westminster Live have alerted us to an interesting debate taking place in the Lords on the issue of litter.

Conservative peer Lord Cormack has told the House: "Those of you who know me will know that I'm not a natural for Glastonbury, at least not for the festival." 

Lord Cormack said he had been told people who go to the music festival "care about the planet" but when he saw the enormous piles of rubbish "we judge people by what they leave behind".

Summing up for the government, Lord Gardiner said littering was "selfish and antisocial", harmed human health and wildlife, and could damage farming and tourism.

He told peers that in March Defra sponsored the first official England-wide community clear-up day. He refers to something several peers have discussed this evening - "the sense of community and doing something together which is so valuable".

The Iraq Inquiry should be wound up and Parliament should decide what to do next with its unfinished report, a former attorney general has said.

Lord Morris told peers the panel led by Sir John Chilcot seemed "incapable" of delivering its report into the 2003 conflict and should be discharged. Read the full story here.

Wednesday's are normally a particularly busy affair at Westminster – and today has been no different. The agenda has largely been dominated by reaction to the Airports Commission’s report, which has recommended a third runway be built at Heathrow airport. And there was also the weekly session of Prime Minister’s Questions. Here are the main developments:

- David Cameron says the government will make a decision on airport expansion by the end of the year

- Several high-profile Conservatives are opposed to Heathrow expansion, including London mayor Boris Johnson, who predicted it "won't happen"

- Labour said it favoured a new Heathrow runway and claimed Mr Cameron was being "bullied by Boris"

- The way child poverty is measured is to be changed to focus on "root causes" of povertyand make a "meaningful change to children's life chances", according to the government

- SNP leader Nicola Sturgeon has topped a power list compiled by BBC Radio 4's Woman's Hour programme

- The outlook for the UK's financial stability "has worsened"in the light of events in Greece, Bank of England governor Mark Carney has warned

- Work and Pensions Secretary Iain Duncan Smith had his official credit card suspended after running up more than £1,000 in expenses debts

And finally, Lib Dem leadership contender Norman Lamb has called for more gay characters to feature in children's television programmes.

Asked if he thinks Gatwick expansion is a credible alternative, the London mayor replies: "If it's a choice between bitten by a dog or a great white shark, you're obviously going to choose to be bitten by the dog," -  adding that Gatwick is the less bad option but not the best solution.

Is it politically possible for the PM to support Heathrow? It will be "very difficult" for him after his "no ifs, no buts" speech, Mr Johnson replies. But it's "more fundamental than that", he adds, saying it's a question of "which is the real choice for Britain".

BBC News Channel

Boris Johnson tells the BBC that Heathrow expansion is "not the right way forward", as it involves "considerable environmental damage" to London and "a huge increase" in noise pollution. "So I don't think it's going to be delivered," he adds.

Other options could yield far more in terms of growth and jobs, he goes on to say - reaffirming his support for a Thames estuary airport.

Patients are to be told how much their medicines are costing the taxpayer under new government plans. The cost to the NHS will be published on all packs worth £20 or more.

Health Secretary Jeremy Hunt told the Local Government Association's annual conference the move would "reduce waste by reminding people of the cost of medicine" as part of wider measures to encourage people to take more personal responsibility for their health. 

About £300m a year is spent on wasted medicines. The new labelling will also see medicines marked "funded by the UK taxpayer" in order to drive the message home. Mr Hunt said:
