As well as warning us what the consequences could be if we don't start living within our means - and reminding us how lucky we are that the Liberal Democrats and some in the Labour Party didn't succeed in taking us into the Euro - it also raises questions about whether what Greece is being asked to do is actually politically deliverable.
I'll be showing it at the public meeting I have organised at 8pm on Friday night at Croydon Town Hall to discuss the Government's deficit reduction programme.
