Hong Kong June 4 vigil organisers urge 'united call for justice'
Hopes of 180,000 turnout at Victoria Park as mainland activists complain of tighter security

Participants in tonight's candlelight vigil in Victoria Park must send a united message to President Xi Jinping that Hongkongers will insist on justice over the Tiananmen Square crackdown, organiser Lee Cheuk-yan said yesterday.
His call for unity came as mainland activists complained that security measures imposed on them were more severe this year, dimming hopes that the new leadership in Beijing would reassess the June 4 tragedy.
Hong Kong journalists in Beijing were also invited to "chat" with public security officers yesterday.
Lee, chairman of the Hong Kong Alliance In Support of Patriotic Democratic Movements in China, which is organising the vigil, said he hopes that at least 180,000 people will turn up at Victoria Park.
"Since Xi took office [in March], the Communist regime has tightened its grip," Lee said.
He said the vigil would "show him that Hongkongers are upset with him as new leader. That's why the turnout is important".
