Pfizer is planning to keep on 650 staff at its R&D centre in Kent, UK, following an announcement to close the facility earlier this year.

In February, the company said that all 2,400 people employed at the Sandwich facility would lose their jobs, before announcing that 350 people would be retained to support the development of products in the mid and late-stage pipeline.

Now, Pfizer plans to keep on an extra 300 staff, reports PharmaTimes.

About 800 members of staff have already left their positions at the renamed Sandwich Discovery Park and a further 700 are set to leave by the end of 2012.
