THOUSANDS of postal workers across the UK will stage a 24-hour strike today and more will join demonstrations in an escalating row over jobs, pay and services, threatening the worst disruption to mail deliveries for years.

The Communication Workers Union said more than 12,000 of its members in areas including London, Edinburgh, Bristol, Darlington and Plymouth would take part in the day of action.

The walkout will be the latest stage in a series of strikes which have hit parts of the UK in recent weeks and is now threatening to escalate into a national dispute.

Royal Mail and the union have blamed each other for the unrest.

Dave Ward, the CWU's deputy general secretary, accused the firm of cutting jobs, freezing pay and hitting services.
