During the 2015 Hong Kong electoral reform, Jeffrey Lam Kin-fung of the BPA and Ip Kwok-him of the Democratic Alliance for the Betterment and Progress of Hong Kong (DAB) led a walk-out of pro-Beijing legislators right before the historic vote on 18 June as an impromptu attempt to delay the division so that his party member Lau Wong-fat, who was delayed, could cast his vote in favour of the Beijing-backed reforms. The government's reform proposal failed as eight legislators voted in favour and 28 voted against, barely meeting the quorum of 35. Since it had been expected the reform would be voted down by 41-28 (which would fall only six votes short of the two-thirds absolute majority stipulated by the Basic Law), the failure in pro-Beijing camp's sudden tactics resulted in a surprising landslide defeat that gave the rest of the world the impression there was no support for the blueprint.
