Britain said Monday progress was being made in negotiations over the future of GM Opel car plants in Britain but there were still issues to be settled.

A German politician said Monday that Germany could end up shouldering the entire burden of aid for Opel because Britain and Spain remained reluctant to support the planned sale of the carmaker to Canadian company Magna.

Some progress is being made in talks between key parties but there are still issues to be resolved, said a spokeswoman for the Department of Business, Innovation & Skills.

We, like everybody else, would like a speedy resolution but we want to get the terms right, she said.

The carmaker, whose British brand is Vauxhall, employs around 5,500 people in Britain, the majority of them at plants in Luton, southern England, and Ellesmere Port in northwest England.
