Letts digs over the week's political news

From the This Week garden, the Mail's Quentin Letts fights off the Saharan sand to dig over the political headlines of the week, looking at the economy, changing opinion polls, Royal Mail shares, Clegg v Cameron over the EU, wind farms, and David Cameron's "Muppets" taunt to the Labour front bench.

Although no animals were hurt in the making of this film, the gardening puns did prompt an apology from the journalist.
