Political and business elites on Friday gathered in Wan Chai to rally for the sole chief executive candidate John Lee ahead of Sunday's vote.

Members of the Election Committee, Lee's campaign advisers as well as district representatives were invited to join the rally at the Convention and Exhibition Centre.

Organisers said around 1,000 people took part.

Addressing the crowd, Lee vowed to unite different sectors of society and build a caring and inclusive Hong Kong that will be full of hope and energy if he's elected Hong Kong's next leader.

"If I am elected, I will bring you a government that will get things done, uphold the constitutional order under the Constitution and the Basic Law, safeguard the core values of the rule of law, protect the foundation of efficient and clean governance, create a safe and stable environment and enhance the overall competitiveness of Hong Kong, so that Hong Kong can take a big step forward without worries," said the former chief secretary.

Former chief executive CY Leung, who's now a vice-chairman of the Chinese People's Political Consultative Conference, said as the world faces great changes in the future, Hong Kong – as part of China – will be presented with both challenges and opportunities. He said the SAR needs to be united and reduce internal conflicts.

Six people, including former police commissioner Tang King-shing, table tennis star Doo Hoi-kem and a secondary school student, were invited on stage to share why they back Lee.

Doo said she hopes under Lee's leadership, there will be more exchanges between young people and athletes in Hong Kong and the mainland to boost sport development in both places.

The secondary school student, meanwhile, said she hopes more youngsters could join exchange programmes on the mainland.
