Port Sunlight is celebrating 125 years. A festival will be held this weekend in honour of the global household goods and food manufacturer Unilever's milestone.
William Hesketh Lever originally set up business in Warrington in 1884, making Sunlight soap before expanding to produce some of the worlds biggest brands including PG Tips and Persil. Lord Lever 64 acres at Port Sunlight into a factory surrounded by a village for it's workers.
Today the grade II listed building still remains. At it's height there were 8000 employees at the site today there are 900 staff.
There are also proposals for a £40m production plant at Port Sunlight.
Unite, which represents some Unilever staff, says it is assessing the impact of today's Unilever announcement.
The firm said it is planning to close plants in Wales and Slough - but invest £40m at its Port Sunlight factory on the Wirral.
Unilever said its plans would "transform" Port Sunlight into a "significant centre of excellence" for the manufacture of shampoo and shower gel products, with growth potential for the next decade.
Unilver says the £40m investment plans for Port Sunlight would create 150 new jobs.
Transfers would increase workforce from 1,500 to 2,000.
