Consumer goods giant Unilever has announced plans to close a number of UK sites including up to 450 in Wales.
The proposals involve the closure of factories in Swansea with the loss of 225 jobs and a distribution site in Bridgend with the loss of 25 jobs.
At Ewloe in North Wales, 400 jobs would be transferred across the border to Merseyside, 100 transferred to Bangalore in India and 100 more lost.
The proposals include plans to invest £40 million in Port Sunlight, its biggest UK factory, on the Wirral, Merseyside, with the creation of 150 new jobs.
The proposed changes, to take effect by the end of 2013, could lead to 500 direct job losses and around 300 contractor and third-party jobs.
