Thousands took to Hong Kong's streets today after Beijing said it would step into an escalating row over whether two city lawmakers who advocate a split from China should be banned from taking up their seats. <br/><br/>The protest follows an ongoing judicial review by Hong Kong authorities, who are seeking to disqualify Baggio Leung and Yau Wai-ching from the Legislative Council over their invalid oath-taking attempts last month, as fears grow that China is tightening its grip on the city. <br/><br/>The government said, Beijing had notified Hong Kong authorities that China's top legislative body would discuss the law which states that council members must swear allegiance to the Hong Kong Special Administrative Region of the People's Republic of China.<br/><br/>The interpretation of Hong Kong's constitution – the Basic Law – by China's National People's Congress Standing Committee is expected to be announced tomorrow.
