Liberal Democrat deputy leader Sir Malcolm Bruce has hailed his party's "extremely good results" in areas where they have concentrated resources.

Sir Malcolm told the Today programme that the party did not need to change their policies, but instead "turn up the volume" so more people hear them.

First broadcast on BBC Radio 4's Today programme on Friday 23 May.
