Whether the doctrine of collective responsibility applies to the Parliamentary Under-Secretary in the Home Office with responsibility for Security, Lord West of Spithead, and the Minister of State for Trade and Investment in the Department for Business, Enterprise and Regulatory Reform, Lord Jones of Birmingham.
