BRITAIN'S chief negotiator for the 1994/95 electoral arrangements, Sir Robin McLaren, will be absent from the most crucial stage of the talks after undergoing an operation in a London hospital for a back problem.
Christopher Hum, the assistant under-secretary of state for Asia and the Far East in the Foreign Office, will take his place to head the British negotiating team when the two sides make last-ditch efforts to try to strike a deal.
Sir Robin, who headed the British team in the past 15 rounds of talks, is expected to take four to six weeks to fully recovery before returning to work.
During Sir Robin's absence, Mr Hum, also an old China hand and intimately involved in Hong Kong issues in his present and previous postings, will take full charge of the talks.
Sir Robin left Beijing on Sunday to join Governor Chris Patten in preparation for yesterday's crucial cabinet meeting to map out the British side's negotiating strategy for what is believed to be the final stage of the talks.
He was scheduled to return this weekend but will now stay in Britain to recover.
