Death, taxes and government changes

It's only a couple of years since the 'good old' Department of Trade and Industry was replaced by the Department for Business Enterprise and Regulatory Reform (BERR). At the same time, the Government established the Department for Innovation, Universities and Skills (DIUS). Now, it's all change again. With immediate effect, we have the Department for Business, Innovation and Skills (BIS) – 'a single department committed to building Britain's future economic strengths'. Was the move to create BERR and DIUS poorly thought out, or has the world changed significantly since then? If it's the former, who's taking the blame? And perhaps the question could be answered of why the DTI needed to go in the first place? But this is probably not the end of it. Many pundits suggest the next Government will be of a different colour and the most likely successor has always had what was the DTI firmly in its sights. Will BIS survive beyond the next election?
