[1][2] The Democratic Alliance for the Betterment and Progress of Hong Kong remained the largest party while the pan-democrats secured the one-third crucial minority.

[3] On 18 June 2015, right before the vote, pro-Beijing legislator Jeffrey Lam Kin-fung led a walk-out of members of the Democratic Alliance for the Betterment and Progress of Hong Kong (DAB), the Business and Professionals Alliance for Hong Kong (BPA), most members of the Hong Kong Federation of Trade Unions (FTU) and other pro-Beijing legislators, leaving five Liberal Party legislators, Chan Yuen-han of the FTU and two other pro-Beijing independents remained in the chamber.

[16] All 27 pan democrats who had vowed to vote down the reform did so, as did one pro-Beijing legislator Leung Ka-lau representing the Medical constituency.

Lam explained that the walk-out was an impromptu attempt to delay the division after the chairman denied his request for a 15-minute recess so that his party member Lau Wong-fat, who was delayed, could cast his vote in favour of the Beijing-backed reforms.

Nine pro-Beijing legislators, including five Liberal Party members, stayed behind out of confusion, and only eight of them voted in favour of the package, giving the rest of the world the false impression there was no support for the blueprint.
