It's almost a week since Jeremy Corbyn was elected as Labour's new leader in a landslide victory for the left-wing MP. But he's yet to win over all of his party, with ex-Labour Chancellor Alistair Darling becoming the latest figure to voice concerns over his leadership.

Mr Darling told told Radio 4's Today programme he was struggling to "see a silver lining" in Mr Corbyn's election and that if he didn't set out where he stands on key policies issues soon, the Labor leader would find it hard to "get off the ground".

Here are some of the day's other political developments:

• Unionist politicians have welcomed shadow chancellor John McDonnell's apology over his IRA comments in 2003 - but questioned his motives.
• In a speech marking the anniversary of the Scottish independence referendum, First Minister Nicola Sturgeon said David Cameron was "living on borrowed time" as he seeks to prevent Scotland leaving the UK
• The government has commissioned an independent assessment of paramilitary organisations in Northern Ireland
• MPs have warned the impact of cuts to policing is not properly understood by either the Home Office or local forces

This morning, during his weekly radio phone-in on LBC, UKIP leader Nigel Farage took a swipe at Jeremy Corbyn over his support for Britain remaining in the EU. Mr Corbyn had initially seemed to leave open the option of Labour campaigning for a Brexit, but after growing pressure from Labour MPs to clarify his position he confirmed he wanted the UK to remain a member of the bloc.

Mr Farage told LBC Mr Corbyn had "completely failed" his supporters after he "surrendered" to pressure, saying the Labour leader privately thought the EU was "awful".

 Mr Farage also criticised Mr Corbyn's appearance at a Battle of Britain commemoration service in London earlier this week, saying he appeared "scruffy" and "frankly on the edge of being slovenly".

The LabourList, external website, reporting comments that Mr Khan made on a visit to a school, said the mayoral candidate expected a "healthy tension" over the issue, stating that "if Jeremy Corbyn has any policies which are anti-business I’ll take him on because we should be encouraging and nurturing a pro-business mentality".

Former Labour Cabinet minister Shaun Woodward says talk of MPs considering defecting following Jeremy Corbyn's election are "pretty premature" and "very unlikely". Mr Woodward, who himself left the Conservatives for Labour in 1999, tells the BBC he thinks it is simply not going to happen. While he agrees with Alistair Darling that the new leader needs to clarify his thinking in key areas and resolve any ambiguities in policy, Mr Woodward says Mr Corbyn is already doing that it his own "non-combative" way. Labour supporters have given Mr Corbyn an "extraordinary mandate", he adds, and the way he has enthused young people has been a "breath of fresh air". "We owe him the chance to succeed".

The SNP's deputy leader Stewart Hosie says his party will never "give up" on independence but acknowledges that there is "no rush" to another referendum and there has to be a "trigger point" or "qualitative shift" in opinion for the question to be put again.

If Scotland was "dragged" out of the EU against its will, this could be the pretext for another vote, he suggests, as many Scottish people will conclude that independence is the "only route to stay in the EU".

But Jackson Carlaw, the deputy leader of the Scottish Conservatives, says the SNP is trying to rewrite history to give the impression that last year's result was narrow rather than the convincing 55%-45% outcome he says it was.

Nicola Sturgeon, he believes, is struggling to manage the "evangelical fervour" of SNP supporters towards independence and suggests her arguments "smack of desperation".

Elections expert Professor John Curtice says all the polling evidence suggests that last year's referendum on Scottish independence was not "decisive". Public opinion, he says, is "evenly divided on the issue of Scotland's constitutional status" - with polls generally showing 52% supporting the Union and 48% backing independence. The polls, he notes, have not changed much in the last year after a well-documented swing of people from the No to Yes camp in the weeks and months after last September's vote. Citing what happened in Quebec, where two independence referendums have been held/ He says the SNP has to be mindful that if it was to lose a second referendum in quick succession then "that will be it" and the question will be settled once and for all.

Jim Sillars, a former deputy leader of the SNP, tells the BBC that a second independence referendum could be held as early as 2017 or 2018 but will almost certainly happen if another Conservative government is elected in the UK in 2020. But Gordon Wilson, who led the SNP in the 1980s, warns against a "rush of blood to the head" which would instigate a vote before the party and Scottish public was ready. He says a lot of preparatory work needs to be done before another vote, on issues like the currency and pensions, which "was not done last time".

In light of recent events in Northern Ireland, the UK government has commissioned an independent assessment of paramilitary organisations. Northern Ireland Secretary Theresa Villiers said the study will determine the "structure, role and purpose" of such groups. It will be conducted by the Police Service of Northern Ireland and the UK security services and will then be scrutinised by three experts to be chosen by the government. To published in mid-October, it will be used to inform parties at Northern Ireland's political talks - which resume on Monday. Read our story here. 

Parliament's youngest MP, Maihri Black of the SNP, has shown off her musical talents in an interview with Channel 4 News. Taking to the piano, she plays the theme from Titanic, and reveals "she always been obsessed" with it.

Ms Black says Scottish independence is "inevitable" - and likely in her lifetime. People voted last year to give the union "another shot", she says, but adds that they'll come to see "the failings" of the Westminster system which "can't give Scotland what it needs and what it deserves".
