An extremely rare jewelled flask given to Clive of India after the Battle of Plassey in 1757 could be exported from the UK unless a buyer can match the £6 million price tag.

Culture Minister Matt Hancock has put temporary export bars on the flask and on Clive's huqqa smoking set, which has a price tag of £240,000, to give UK buyers the chance to save the Mughal treasures for the nation.

Robert Clive, known as Clive of India, was governor and commander-in-chief of India and became famous for his victory over the Nawab of Bengal during the Battle of Plassey in 1757.
