Professor Tim Evans of Middlesex University looks at the state of the UK economy in the wake of the Spring Statement. He looks at taxes, tariffs and debt, pointing out that despite the perceptions of many, the UK is a high-tax economy. He explains why the Conservatives are reluctant to get rid of the deficit entirely. And, as a new book is published, he looks at Chernobyl and the way in which - it now appears - the Soviet Union minimised and covered up the extraordinary extent of the disaster.
