Mr Hain is also backed by Home Secretary David Blunkett and the Cabinet. He wants a Director of Security appointed to oversee both the Commons and the Lords, which have separate authorities, and to work closely with MI5 and Special Branch. Currently authority over the Commons belongs to the Speaker and his chief official, the sword-wearing Serjeant at Arms, both of whom wear black tights as part of their robes. In the Lords, the Lord Chancellor and Black Rod are in charge.
