EARLIER this year, Governor Chris Patten started talking publicly and confidently about internal splits in the Chinese leadership over policy towards Hong Kong.
His statements were aimed at giving him the upper hand in his continuing battle with Beijing and driving a wedge of doubt, suspicion and uncertainty between his adversaries in Beijing and in the territory.
In the constant ebb and flow of Sino-British negotiations he may have gained some leverage by catching them wrong-footed in the hope of gaining valuable ground at the bargaining table.
But was this political brinkmanship or an astute move backed by information of China's negotiating position culled through intelligence? Politically, and to some extent militarily, Hong Kong and China have become the focus of British and United States intelligence services, which generally share information of the region.
A continually ticking global intelligence machine gathers, intercepts and assesses everything from takeaway orders to potentially crucial information from a host of agents, ''along siders'' or unpaid informers and signal sources.
The brunt of the information comes from a shadowy establishment organisation known in intelligence circles as ''Box''.
