High street transformed by soaring retail outlets closures

The number of stores closed by retail chains in Britain has soared over the past 12 months, according to research.

Analysis from PwC and the Local Data Company revealed that the chains shut an average of 20 shops a day last year.

The figure increased in the last three months of 2012 as a spate of household names went into administration.

The BBC's business correspondent Emma Simpson is in Preston to see the effect big name closures are having on the rest of the high street.
