TRADE unions welcomed a major boost to Britain’s economy today after Jaguar Land Rover announced it will be building electric cars in the West Midlands.

The company confirmed it will be retooling its factory in Castle Bromwich to allow electric cars to be assembled at the plant.

A version of the Jaguar XJ sedan will be the first all-electric vehicle scheduled to be built by the company’s 2,500 workers — and Castle Bromwich will be the first such plant in Britain.

Unite union assistant general secretary Steve Turner has welcomed the “trailblazing” decision, and said that the “skill and hard work” of Unite members and shop stewards is to thank for the announcement.

Mr Turner said: “Not only is it a fantastic boost to the British car industry, but it ensures that Jaguar Land Rover’s Castle Bromwich site remains a powerhouse of the regional economy, providing a living for thousands of workers and supporting many more in the supply chain.

“This is a proud day for our members and Jaguar Land Rover.

“The government and Theresa May’s replacement as prime minister must make sure it is not the last for Britain’s world-beating car workers and their families.”

Labour shadow business secretary Rebecca Long Bailey said: “This is welcome news for the workers at JLR and a ray of hope for the automotive sector at this difficult time.

“However, the fact remains that overall investment in UK automotive is plummeting and global players are choosing to invest in electrification elsewhere.

“The government must urgently work with industry and trade unions to ensure this investment from JLR is a model to other manufacturers and not an exception.”

Business Secretary Greg Clark said that the announcement was a “vote of confidence” in British industry, and reflects the government’s “determination for the UK to be at the forefront of the development and manufacturing of the next generation of electric vehicles.”

The plant will close for six weeks so that new works equipment can be installed, and workers have agreed to work a four-day week as part of restructuring plans.
