Postal workers have voted in favour of a national strike in a bitter row over jobs, pay and services, threatening widespread disruption to mail deliveries in the coming weeks.

The Communication Workers Union said its members backed a nationwide walkout by 3-1 in protest at the "imposition" of changes to working practices as well as cuts in their pay and job losses.

The action is likely to take place later this month.

However, postal workers in Swindon start their 24-hour walkout at 4am tomorrow in a dispute over working practices.

The strike is likely to have a huge impact on weekend deliveries in Oxfordshire.
