Shares in music retailer HMV have jumped by 17% after the group confirmed it had received a takeover approach.

According to the reports, Permira has hired Merrill Lynch to advise it on a possible £800m ($1.4bn) takeover.
The news saw HMV's shares recover from lows hit last week after the retailer reported a fall in sales and profits.

Analysts blamed online competition and aggressive supermarket pricing policies for HMV's festive troubles.
European-based Permira is no stranger to UK buyouts. In 2001 in bought DIY chain Homebase - which was later sold on to Argos-owner GUS - and in 2003 it snapped up the Travel Lodge hotel business and roadside restaurant chain Little Chef.
In a statement, HMV said it had "received a preliminary approach from a third party which may or may not lead to an offer being made".
