Key talks between Royal Mail and Union bosses to try to prevent national postal strikes are expected to resume today.

Communication Workers Union senior representatives reportedly spent 12 hours thrashing out negotiations with Royal Mail managers at a secret location in central London.

Union sources say it's a positive sign that the talks are still ongoing, while a Royal Mail spokesperson says that the company is working hard to prevent this week's planned strikes.

It comes after the Union voted three to one in favour for a national strike earlier this month.
