Sixty workers are on strike for a second day at Didcot power station in support of protests against the use of foreign labour at the Lindsey oil refinery in Lincolnshire.

An spokesman for RWE npower, which owns the power station, confirmed the workers – all contractors working on maintenance projects at Didcot A Power Station – were striking for the second day, but said no npower staff were involved.

Eighty workers downed tools at 1pm yesterday.

Nearly 900 workers constructing a new plant at the Lincolnshire refinery were sacked following unofficial strike action yesterday.
