Tristram Hunt: 'High quality teaching is key'

Almost 3,500 schools in England rated as "requiring improvement" face being forced into new leadership, under plans to be announced by David Cameron.

He will promise that if the Tories win the May general election they will tackle "coasting" schools that are failing to make sufficient progress.

But speaking to the BBC, Shadow Education Secretary Tristram Hunt suggested that the key to improving standards was to have "really high quality teaching in the classroom" and accused the government of allowing "more and more unqualified teachers".
