Patrick Brown caused considerable controversy as PCYF president in 1999 when he pushed for the merger of the right wing movement despite the objection of Tory leader Joe Clark. This move eventually led to PCYF aggressively pushing a united right during the tenure of Brown's presidency. Brown faced considerable opposition from some members of the senior party who were hostile to a united right. Brown campaigned on TV along with Adam Daifallah for the united right. These activities were consistent with a long history of PCYF activism that made lasting contributions to Canada's political democracy, including the removal of John Diefenbaker by Dalton Camp, the adoption of Leadership review as a process to enshrine accountability, the leadership selection of Brian Mulroney and Kim Campbell.
