Edinburgh International Festival concert cancelled after power failure

The Edinburgh International Festival was forced to cancel one of its biggest concerts following an electrical fault.

The problems affected a performance which was due to take place at the city's Usher Hall on Tuesday.

The concert, featuring Russian singers, the London Philharmonic Orchestra and the Edinburgh festival chorus, had a bell-themed programme.

Festival organisers apologised to concert-goers and have offered a full refund on tickets.

The power failure happened at 19:30, about 30 minutes before the concert was due to start.

A Scottish Power spokesman said there had not been a power cut in the area.

"Our engineer was called at 19:52 and arrived at the Usher Hall at 20:50," said the spokesman.

"He confirmed at 21:30 that there was no fault on the Scottish Power network."

It is understood that there was a problem with the building's internal wiring.

An Edinburgh International Festival spokeswoman said they were "hopeful" Wednesday's performance would go ahead as they had sourced a generator.
