A spokesman for the German engineering group said on Tuesday the cuts would take place over four years and there would be no compulsory redundancies.

Siemens had said in March it would cut around 2,500 jobs worldwide in areas related to the oil and gas, metals and mining sectors, of which about 2,000 would be in Germany.

It expects restructuring charges of 250-300 million euros (£217-261 million) for the layoffs.
