Thomson ReutersHONG KONG (Reuters) - A small electoral college chooses a new Hong Kong leader on Sunday amid accusations of meddling by Beijing, denying the Chinese-ruled financial hub a more populist leader perhaps better suited to defuse the political tension. The vast majority of the city's 7.3 million people have no say in their next leader, with the winner to be chosen by a 1,200-person "election committee" stacked with pro-Beijing and pro-establishment loyalists. Three candidates are running for the top post, two former officials, Carrie Lam and John Tsang, and a retired judge, Woo Kwok-hing.
