British technology firm Dyson today accused its German rival Bosch of planting a mole in its high-security research and development department for as long as two years.

Dyson founder Sir James Dyson filed proceedings at the High Court claiming a Chinese employee at its research and development centre in Malmesbury, Wiltshire, was giving company secrets to Bosch.

Bosch, which has its UK headquarters based in Middlesex, declined to comment.
