On July 1 next year, Hong Kong’s third chief executive since the handover in 1997 will take office. Beijing has decreed that it could be the bland Henry Tang or the earnest CY Leung. No other candidates need apply. The right to choose Hong Kong’s next leader is confined to a 1,200-member college of electors which will be in place by December. They represent 0.01 percent of the population. Each 'constituency' is assigned a fixed number of block votes. Any candidate wishing to be considered must collect a minimum of 100 nominations.
