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

Like my right hon. Friend, I am keen that we do not have some great bureaucratic invention to deal with this issue. There is one thing I do not understand, however. If a public relations company that has 500 clients comes to speak to my right hon. Friend or a Secretary of State or a permanent secretary, what would be the difficulty in making it a requirement that the company makes it clear which client it is coming to speak on behalf of? Otherwise, one does not get very much further by just knowing which company is making the representation.
