Pro-establishment lawmakers are under pressure to salvage their shattered unity after Beijing's top representative in Hong Kong called on the culprit who leaked WhatsApp messages to stop the exposés, which have ruined trust in the camp. Liberal Party chairman Felix Chung Kwok-pan, one of the 40 Beijing-loyalists who met liaison office director Zhang Xiaoming at a "tea gathering" on Thursday, said those present agreed to stop trying to trace the whistle-blower who betrayed chat messages circulated among the camp during last week's historic electoral reform vote. "When we met Zhang, we felt we should condemn the person who leaked the messages," Chung said yesterday. "Zhang said the leak had ruined mutual trust in the WhatsApp group and hurt friends. He urged the leaker to stop. … The consensus was not to hunt for the guy any more." The office director was meeting Chung and the other Beijing loyalists for the first time since they bungled the legislative vote. But the expected focus of the gathering on their blunder was overshadowed just hours earlier when messages from their WhatsApp group appeared in the Chinese-language Oriental Daily News and were authenticated by Legislative Council president Jasper Tsang Yok-sing. Messages published on Oriental Daily 's website around midnight on Wednesday showed Tsang discussing strategy with allies while in Legco on June 18 - leading pan-democrats to question his neutrality. Then, on the website in the afternoon, the city read about the camp's discussion of how to clarify its walkout, including whether to use the word "apology". Despite Zhang's call, the newspaper revealed a third batch of messages at midnight, this time involving local deputies to the National People's Congress, the state's top legislature.

Martin Liao Cheung-kong, who is also a lawmaker, messaged colleagues that the failure to vote was due to "pure stupidity, bad leadership". NPC deputy and lawmaker Ip Kwok-him verified the messages. "The messages were copied from the NPC chat group by Martin Liao Cheung-kong and pasted into the pro-establishment lawmakers' chat group on the day of the vote," Ip said. "He had meant to let his [Legco] colleagues know the NPC deputies' reactions. The NPC group itself was not leaked." Liao declined to comment, saying only that the disclosure was "immoral and unjust". Cheung expressed "strong dissatisfaction" at the revelation. Meanwhile, more lawmakers denied being the whistle-blower, including independents Paul Tse Wai-chun and Ng Leung-sing. New People's Party chairwoman Regina Ip Lau Suk-yee showed the media her BlackBerry phone, which she said was too old to use the latest version of WhatsApp. Party colleague Michael Tien Puk-sun, invoking a traditional Chinese curse, said whistle-blowers should be "damned to the 18th level of hell". Tse, Ng and Liberal Party leader Vincent Fang Kang agreed to set aside the leak issue and focus on strengthening cooperation within the camp. Tsang agreed there should be no witch-hunts, adding: "The important thing is … to unite." The camp's walkout, seconds before the vote on the government's reform plan for the 2017 chief executive election, led to a historic defeat, with only eight votes in favour and 28 against, causing Beijing embarrassment. Meanwhile journalists were sharing stories of their rare glimpse inside the liaison office after being invited to wait in the lobby on Thursday. Many noted the snacks on offer - biscuits from Taiwan, not the mainland.
