The coalition is determined to push through a shake-up of lobbying rules before 2015, constitutional reform minister Mark Harper said today.
Harper dismissed suggestions that plans had been put on the back burner, insisting a White Paper and draft Bill would be published during this parliamentary session.
David Cameron has been hit by a series of lobbying rows since he described the industry as the "next big scandal waiting to happen".
But questions were raised about the Government's commitment to introducing a statutory lobbyist register after no proposals were included in the Queen's Speech.
Giving evidence to the Commons political and constitutional reform committee, Harper said: "We may not be going as fast as some people would like, but we have discovered ... that the devil is in the detail on this subject."
He added: "We are taking a sensible approach but we are determined to get it done in this parliament."
