SWINDON'S post offices have taken delivery of this year's Christmas stamps.

And this year there is an even greater incentive to use traditional mail when sending your Christmas greeting.

A unique diamond stamp has been delivered to a secret location somewhere in the UK.

And anyone who buys 12 or more of the Christmas stamps will be in with a chance of scooping £1 million.

There are also 30 runner-up prizes.

Hidden in gamecards, which look like enlarged stamps, there are five £50,000 ruby prizes and 25 £10,000 sapphire prizes.

The stamps themselves are self-adhesive for the first time at Christmas.

They feature festive snowy scenes with traditional red-breasted robins.
