That's it for first minister's questions this week. It will be back next Thursday, usual time, usual place.

• Methadone should continue to be used to treat heroin addicts in Scotland, a review commissioned by the Scottish government concluded in 2013., external

• The Scottish Drugs Strategy Delivery Commission also said the system used to reimburse pharmacists for dispensing methadone should be reviewed.

• Methadone has been at the heart of drug treatment strategies since the 1980s.

• But its use had been widely criticised by recovering addicts and drugs workers.

Tory MSP Margaret Mitchell asks if there's still a place for methadone to help heroin-users kick their habit. FM says there is.

The Scottish government is facing calls to delay changes to Advanced Highers. They are due to be revamped later this year in the latest stage of the ongoing shake-up of qualifications.

The SSTA union said the current version of the qualification should also be on offer next year and accused the Scottish government of a lack of respect for teachers' judgement.

But the government said it had not yet heard a "compelling case" to do this.

FM says, in response to Labour's Iain Gray, that there are no plans to allow new advanced highers to be postponed. But FM says she'll continue to monitor the issue. Mr Gray said there was concern from teachers about the new qualification.

The SNP's Christina McKelvie asks how public services can be maintained under UK government "austerity cuts". FM says it's making things hard.

FM says police must be supported in their work. She points out that force representatives are giving evidence to a Scottish Parliament committee later today.

WR says he want's FM's opinion on senior police officers "failing to be straight" and says trust in Police Scotland has been "shattered".

MSPs will take evidence on stop-and-search from Chief Constable Sir Stephen House from 1pm, which we will be covering here at Democracy Live.

Assistant Chief Constable Wayne Mawson from Police Scotland, Calum Steele, from the Scottish Police Federation and Vic Emery and John Foley from the Scottish Police Authority will also give evidence.

Police Scotland must give an "honest explanation" for the "sorry mess" over its handling of data on stop-and-search, an MSP has said.

Lib Dem MSP Alison McInnnes is a member of the Scottish Parliament Justice sub-committee on policing that will quiz senior officers later.

She said the facts on stop-and-search did not match the claims of Chief Constable Sir Stephen House.

Labour's Hugh Henry said Sir Stephen had "some serious questions to answer".

FM says police are now considering ending the use of stop-and-search.

Liberal Democrat leader Willie Rennie (WR) raises concern about the conduct of senior police officers over the use of stop-and-search tactics.

The UK government's Business Secretary Vince Cable has said there is no threat to the security of Scotland's electricity supply.

His comments came after BBC Scotland's disclosure that the huge coal-fired power station at Longannet in Fife was facing a renewed threat to its future.

Mr Cable said energy could be imported from England.

Scotland's Energy Minister Fergus Ewing told BBC Radio Scotland that Longannet was necessary to "meet demand".

Scottish Power, which operates the plant, warned last year that the cost of connecting to the grid meant the power station may close earlier than planned.

In response to a constituency question, FM says the UK government needs to intervene to secure the future of the coal-fired power station at Longannet in Fife.

FM says she want's to maintain teacher numbers and says Labour and Tories should be telling their councillors to back the policy.

RD says parents are "watching in horror" as councils and ministers fight over the "basic task" of hiring teachers. She asks FM to back a new law allowing schools to opt-out of local authority control.

FM says she'd be happy to look at the issue, but suggests the old school-opt policy - a Conservative one - was not popular.
