There are many imperfections in the workings of the British constitution: we do not live in a democracy, we do not have an elected head of state or an elected upper Chamber, and we do not have an accountable judiciary. We have only an elected House of Commons, in which the Prime Minister can use the royal prerogative virtually to pass legislation. Indeed, the Government were legally advised that the Maastricht treaty could be passed in that way. However, there is some accountability for what the Executive are doing in terms of foreign and defence policy. Under the Maastricht treaty, with a common foreign and defence policy, that accountability will not exist. It will not exist in the European Parliament, which can question but not call to account. It will not exist here, because we shall always be told that policy is being made somewhere else.
