Tabasco sauce producer McIlhenny is marking the Queen’s Diamond Jubilee with limited-edition packaging.

The Jubilee packs - a red, white and blue box featuring diamond artwork (rsp: £1.49) - will roll out in May.

The launch will be supported by an on-pack promotion giving one consumer the chance to win a diamond.

A competition on Facebook will run alongside the on-pack promotion, offering prizes to followers every day for six weeks until 30 June.
