ITV News plans to cut 430 jobs across the UK
Up to 34 jobs are to be cut at ITV Anglia Tonight as part of plans to merge its east and west programmes into a single pan regional show.
A spokesman for ITV said staff at the news channel, which covers the East of England, were being given the chance to take voluntary redundancy.
But compulsory job losses could not be ruled out, he said.
ITV said the quality of local news would not be damaged by the move, but unions have criticised the plans.
The announcement is part of ITV News' plans to cut 430 jobs in its regional news service across the UK to reduce costs as advertising revenue slows.
A spokesman for ITV said the single regional evening and late news will have east and west opt outs - featuring more local news. About 70 members of staff are being retained.
He added that ITV was investing in digitising local services and providing ITV Local internet service.
Unions have criticised the proposals for ITV and warned they would fight the job cuts.
Laura Davison, assistant broadcasting officer of the National Union of Journalists, said she could not rule out industrial action.
"We do not accept the level of cuts ITV News wants to make and it is difficult to see how we can avoid a fight over this."
Anglia Tonight, which has its main office in Norwich, also has offices in Ipswich, Luton, Chelmsford, Cambridge, Peterborough and Northampton.
