Up to 70 sub contractors went on strike at the Sizewell A and B power stations in Suffolk today.

The workmen walked out in support of industrial action taking place at a Lincolnshire oil refinery in a row over the use of foreign workers.

Between 30 and 40 workers downed tools at Sizewell B, and between 25 and 30 also took action at Sizewell A.

There was a picket line this morning and one irate sub contractor said: ''There should be British jobs for British people - but instead they are bringing in foreign workers and giving them jobs.

''Somebody has to take a stand over this and this is what we are doing.''

A British Energy spokesman confirmed that action was taking place among the workforce of two companies providing labour at Sizewell B.

He added that health and safety issues at the nuclear power plant were not affected.
