Tom Jones and Jennifer Hudson on The Voice, Art galleries on screen

Sir Tom Jones and Jennifer Hudson discuss mentoring the competitors in the TV talent show The Voice, how they coach their protégés and where the value of knockout singing competitions lies. Kirsty visits rehearsals at the studios of the television show and talks to the two judges.

As The Square, a satire on modern art galleries hits cinemas, we consider the portrayal of the art gallery in film with Briony Hanson, Head of Film at British Council, and art critic Jacky Klein who also works at Tate.

As 'embiggen', a word coined by The Simpsons, makes its way into the dictionary, lexicographer Susie Dent traces the way words hop from the screen into people's conversations and their impact on our language.
