They don't call him 'Bow-tie Tsang' for nothing. Our acting chief executive has long been known for his style in neckwear, but CitySeen wonders if Donald Tsang Yam-kuen was also using his bow tie to send subtle political messages on the eve of his appointment. In this photo taken on Friday, Mr Tsang is sporting a very rare example - the Royal Over-Seas League bow tie. As the founder and president of the league's Hong Kong branch, Paul Surtees, told CitySeen: 'There are only three of them in the SAR.' One belongs to Mr Surtees, another was presented to British Consul-General Stephen Bradley and the third was given to Mr Tsang when he addressed the league a couple of years ago at a lunch at the China Club. Was it an inadvertent choice, or was Mr Tsang deftly signalling a return to the good old colonial days? Then again, it is possible he was just early in celebrating Commonwealth Day, which is today. The league, as one would expect, will host a reception this evening for the occasion, this time at The Peak home of New Zealand Consul-General Frank Wilson. Consuls-general from Commonwealth countries are expected to attend, as are members of Commonwealth societies in Hong Kong. Mr Surtees told CitySeen the league had invited Mr Tsang but he was unable to accept. Well, he does seem to have a lot on his plate at the moment, what with the new job and all.
