More than 600 homes have been left without electricity after an unplanned power cut. 

People in and around Diss have woken up this morning to no power. 

A spokesman for UK Power Networks said: "We’re sorry for any disruption this may have caused you.

"We didn’t know in advance there would be a power cut, but now that we know, our teams will do everything they can to get your power back quickly."

It is not yet clear when power will be restored.
