Siemens today said it had won a contract worth €350m to supply wind turbines for what it described as Europe’s largest wind farm, to be built in the UK.

As many as 10,000 Siemens AG employees demonstrated yesterday against plans by Germany’s largest engineering company to shift some production abroad to help cut personnel costs.

Siemens AG, Germany’s largest employer, plans to increase work hours for an additional 19,000 employees to boost profitability, German daily Die Welt said.
