【明報專訊】BARRY CHEUNG CHUN-YUEN has resigned from all his public offices, the most important of which is undoubtedly the office of executive councillor. Over the past few days, there has been much discussion about the Executive Council. Legislative Council president Jasper Tsang Yok-sing, for one, said Exco's role today is less important than it was in the colonial days. The implication seems to be that a thorough review of Exco's role and functions is required.
