BBC investigation has revealed a catalogue of errors in call handling by Police Scotland.

More than 80 "near misses" have been recorded in police call centres since April.

Files show staff mishandled 999 and 101 calls involving road traffic accidents, domestic abuse, assault, self-harm, and vulnerable children and adults.

Police Scotland said these incidents accounted for only one in every 22,500 calls.

The logging of "near misses" follows Police Scotland's failure to act on a 101 call about a car crash on the M9 last year. The crash resulted in the deaths of Lamara Bell and John Yuill.

Ms Bell, who was discovered critically injured in the crashed car, had been in the vehicle next to her dead partner Mr Yuill for three days. She died later in hospital.

A subsequent HM Inspectorate of Constabulary report, external found examples of call handlers being under pressure to end calls quickly and grading of calls being dependent on resources available.

Lib Dem MSP Liam McArthur asks the Scottish government what action is being taken to reduce the number of "near misses" that are being recorded by police control rooms. 

Reverend Nigel Anderson from the Livingston Free Church gives today's time for reflection.  

Keir Bloomer, of think tank Reform Scotland and chair of the Commission on School Reform, said the education system was now in urgent need of action.

He said: "It is no longer credible to describe Scotland's education system as world leading.

"There is a critical and urgent need to examine how Scottish education is run, and the Scottish government's stated intention to empower teachers, parents and schools must be matched by action."

Opposition parties said the results showed a "decade of educational failure" under the SNP government, with First Minister Nicola Sturgeon previously saying she wanted to be judged on her record on education, external.

Teachers called for a "period of stability" following the results, which saw Scotland fall from "above average" in reading and science to "average".

The Pisa testing system was set up in 2000 among countries from the Organisation for Economic Co-operation and Development (OECD).

Half a million 15-year-olds took part in the latest round of tests, which cover literacy, numeracy and science, in March 2015.

Ross Greer of the Scottish Greens said: "This drop in performance is clearly a concern. We need to listen to teachers and invest in what they know will make a difference - namely more staff and a simplified workload following years of changes, so that they have more time to connect with their students."

And Tavish Scott of the Lib Dems said there was "no escaping the fact that surveys show the SNP have overseen a worrying decline in our education system"

Scottish Labour said Scotland's OECD rank in reading had gone from 6th in 2000 to 23rd in 2015, from 9th in mathematics in 2003 to 24th in 2015 and from 10th in science in 2006 to 19th.

The party's education spokesman Iain Gray said: "SNP ministers should be ashamed of these results. For all their warm words about making education a priority we are seeing performance going backwards as Scotland drops down international league tables."

Scottish Conservative education spokesman Liz Smith said the "shocking statistics" were a "damning indictment of a decade of failure under the SNP".

She added: "The fact that the SNP has been so obsessed with independence has meant that it has taken its eye completely off the ball when it comes to education.

"Nicola Sturgeon says she wants to be judged by her performance on education but parents will rightly wonder what on earth her Scottish government has been doing for the last 10 years.

"Children going through our schools under the SNP are finishing their school careers less equipped in basic skills and performing less well than their counterparts elsewhere in the UK, and in a host of other countries across the world."

Scotland's schools have recorded their worst ever performance in an international survey of pupils.

Scotland's scores for maths, reading and science all declined in the latest set of Programme for International Student Assessment (Pisa) figures.

Mr Swinney, who will make a ministerial statement at Holyrood on the results at 2.20pm pledged an "unwavering focus on improvement".

He said: "There is great strength in Scottish education but these results underline the case for radical reform of Scotland's education system.

"The results undoubtedly make uncomfortable reading but they contain a plain message: we must continue to make the changes that are necessary to strengthen Scottish education.

"We must recognise that while Pisa is only now being published, it dates from the period in which our own statistics on literacy and numeracy were published and prompted our current programme of reform. Both sets of figures tell us the same thing. Reform is essential.

"That is why last year we launched a comprehensive programme of reform, based firmly on the independent findings of the 2015 OECD review of Scottish education. It is by carrying through on these reforms - no matter how controversial - that we can make Scottish education world-class again.

First up this afternoon we have topical questions with the issues of 'near misses' recorded by police control rooms and the ban on smoking in cars with children present being raised. 

Education Secretary John Swinney will then respond to the worst ever performance in an international survey of pupils.

Public Health Minister Aileen Campbell says Scotland takes the lead in youth work compared with other parts of the UK.
