A 22-year-old former public servant who became one of the nation’s most “successful” lobbyists is dumped by almost all his clients.

The owner of a spectacularly successful “lobbying” firm launched by a 21-year old Young Liberal after working for the former NSW Planning Minister is a mystery.

One of two brothers of the NSW Premier to have gone “missing” allegedly sought $50,000 to “revenge unseat” a federal minister.
