Electricals chain Comet has been officially placed into administration.
Neville Kahn, joint administrator and restructuring services partner at Deloitte, said:
Our immediate priorities are to stabilise the business, fully assess its financial position, and begin an urgent process to seek a suitable buyer which would also preserve jobs.
In the meantime, all stores will continue to trade and all employees will continue to be paid.
We appreciate the co-operation and support from the management, staff, customers, landlords and suppliers at what is clearly a very difficult time.
The large distribution hub in Harlow in Essex has become the biggest Comet site so far to close, with 172 people losing jobs.
Around 6,500 retail jobs are under threat as electricals chain Comet became the latest casualty on the high street.
