A chain of children's nurseries and day centres has gone into liquidation, leaving 136 staff facing redundancy.
Up to 450 families will be affected by the closure of the Great Yarmouth Community Trust, which ran eight nurseries and two other education facilities across Norfolk and Suffolk. All of them are now closed.
Administrators said the trust had "serious financial difficulties" and stopped trading on Wednesday.
Lee Green, Partner at MHA Larking Gowen, which is advising the trust and handling the liquidation, said:

Norfolk and Suffolk County Councils say they'e working to provide alternative nursery provision as quickly as possible.
Norfolk County Council has set up two new companies, one to run provision at Horatio House and the other to run nursery provision in Norfolk.
Drop-in sessions are also being held for parents in Great Yarmouth and Gorleston on December 4th.
A spokesman said: "We hope to have some Norfolk nursery provision up and running by mid December and the independent school provision open by January 6."
The council is also holding special sessions for staff on December 3 to talk about future employment.
A special number has been set up for parents to contact on 01603 306300. It is open until 7pm tonight and from 8am tomorrow morning.
