[LONDON] Royal Mail Plc said on Friday that it would apply for an interim order from the High Court to block a potential strike by its biggest union, the Communication Workers Union, saying it believed the strike ballot had been unlawful.

Royal Mail said it was worried by the potential for industrial action around the General Election on 12 December and in the traditionally busy run-in to Christmas.

The CWU last month voted by 97 per cent in favour of a nationwide strike, saying the company had failed to adhere to a pension deal agreed last year. Royal Mail said it had honoured the deal.
