HMV, Britain's biggest music, video and book retailer, has given details of its planned flotation on the London Stock Market, which is set for 15 May.

It is pricing its shares at between 190 pence and 220 pence.

The share price in the middle of that range would value the company at �834m.

HMV would raise �351m from the sale, which it wants to use to cut debts.

The High Street chain is 43 per cent owned by the music company, EMI.

The first HMV store was opened in 1921 and it is named after its trademark image of Nipper the dog listening to 'His Master's Voice' on a gramophone.
