Up to 85 jobs are understood to be at risk at a Bradford manufacturing plant due to a review of its operations.

Bosses at Switchgear & Instrumentation in Ripley Street, West Bowling, will reportedly start consultations with workers on Monday about possible cuts.

Richard Fearnside, head of human resources, said the firm was considering up to 85 possible redundancies.

S&I, part of the Houston, Texas-based Powell Electrical Group, designs and manufactures switchgear, motor control and power management systems.

In 2005, when S&I was bought by Powell from the Ilkley-based NG Bailey group the firm employed about 300 people. At the time of the deal Powell pledged to continue investment at S&I's Ripley Road site in a bid to increase sales in Europe and the Middle East .

About 85 jobs were cut at S&I in 2004 through a restructuring aimed at fighting off competition from overseas.
