Anson Chan
Martin Lee actively lobbied in the West with former Chief Secretary for Administration and Hong Kong 2020 convenor Anson Chan for the support in the Hong Kong's democracy movement during the debate on the 2017/2020 electoral reform in 2014. The duo went to the United States and met Joe Biden, US vice-president, Nancy Pelosi, minority leader of the House of Representatives, and members of the Congressional-Executive Commission on China and spoke out against Beijing increasing control over Hong Kong and their fear of only candidates picked by Beijing would be allowed to take part in the 2017 Chief Executive election. In July 2014, Martin Lee and Anson Chan visited the United Kingdom and met with Deputy Prime Minister and the leader of the Liberal Democrats Nick Clegg and attended a Foreign Affairs Select Committee hearing, speaking out that they were "concerned that neither of the two signatories to the Joint Declaration – that is, China and Britain – is adequately fulfilling their respective responsibilities on the terms of this internationally binding treaty." Liu Xiaoming, Chinese ambassador to Britain, described Martin Lee and Anson Chan as "bent on undermining the stability of Hong Kong".
