Transparency of Lobbying, Non-Party Campaigning and Trade Union Administration Bill

Can my noble and learned friend clarify what he has said? If a consultant lobbyist lobbies a Minister directly to achieve policy X, that consultant lobbyist must register. If that consultant lobbyist only lobbies the special adviser, who then advises the Minister, who decides to implement policy X, they do not have to register. The second point is on civil servants. Does he think that lobbyists will lobby any passing civil servant as opposed to those members of the senior Civil Service who have responsibility in particular areas, and are therefore a very narrow and usually clearly defined group?
