On December 14, 2011, the ADQ announced it had agreed to merge with the CAQ, pending final approval from the party membership. On January 21, 2012, the ADQ membership approved the merger of their party with the CAQ , with 70% of the party membership voting to merge. The remaining ADQ MNAs, all of which supported the merger, were expected to join the larger CAQ caucus in the National Assembly, increasing the CAQ caucus size to nine members and increasing the pressure on Charest to call an election. On 22 January 2012, the results of the mail-in vote were announced, with 70% of ADQ members approving the merger with the CAQ. In mid-December, after the parties had agreed in principle to merge, two former ADQ MNAs who had left to sit as independents joined the CAQ.
