Parents and pupils will have to wait another week to find out about the repairs timescale for Edinburgh's closure-hit schools.

The city council's chief executive Andrew Kerr hit out at the Edinburgh Schools Partnership (ESP) for the length of time it was taking to receive clearer answers on the 17 properties affected by the crisis.

ESP, which operates and manages the schools built under the PPP project, has told the city council that details of how long the venues will be closed will not be available until the end of next week.

Mr Kerr said on Friday he was "disappointed" by the delays in survey results from ESP, which is responsible for undertaking the required repairs.

Parents had previously been told there would be a clearer picture on the timescale of closures and repairs by the end of this week.

He said: "We have been in constant dialogue with the Edinburgh Schools Partnership and they are aware of our concerns.

"It is important that we have clear information regarding the condition of these schools and when they will be safe to reopen.

"I know that parents, teachers and pupils will share my frustration at this delay. The safety of our children is our number one priority and we all want our schools to reopen safely, as soon as possible.

"We are doing everything we can so ESP can provide the council with the information which will allow us to make a decision regarding the next steps."

The city council closed the 17 schools after the Easter holidays after structural faults were discovered. The closures affected 7600 pupils, plus more than 700 nursery children.

All youngsters affected by the crisis resumed lessons on Wednesday but many of them remain in temporary classrooms.

The schools were all built or refurbished under the same public private partnership (PPP) schemes around ten years ago.
