Shenzhen Mayor Yu Youjun yesterday tried to play down the impact of a graft investigation into former deputy mayor Wang Ju. Mr Yu said only a handful of municipal officials were implicated in Wang's case, adding Wang was still being investigated by the party's anti-graft watchdog. But he declined to comment on when any prosecution might begin. Mr Yu said the scale of the case was relatively small compared to other corruption cases. 'It is nothing like the case in Zhanjiang,' said Mr Yu. 'Only a few department directors and division heads were implicated [in Wang's case],' he said. Dozens of officials were arrested after a government investigation into smuggling activities in Zhanjiang, Guangdong, last year. Mr Yu, speaking outside a committee meeting of the Guangdong People's Congress, said there would not be any major reshuffle at the Shenzhen People's Congress meeting next month. Mr Yu's comments seem to hint that it is unlikely more officials will be implicated in the case. Former Shenzhen party boss Li Youwei, one of the conveners at yesterday's meeting, also denied speculation in the press that he was implicated in Wang's case. 'The speculations are all fabrications. If the media reports are true, I would not have been here,' Mr Li said. He is now the standing committee member of Shenzhen People's Congress. It was the first interview he had given to Hong Kong reporters since Wang - reportedly a close ally of Mr Li - was detained. Wang was reportedly under investigation for receiving kickbacks for giving out contracts when he was the deputy mayor. He was also said to have been accused of favouring his daughter's and son-in-law's real estate interests in Shenzhen. Separately, former Zhuhai party secretary Liang Guangda also denied reports he had been questioned by the central Government's graft watchdog. Mr Liang was Zhuhai party secretary during the 1980s and was widely perceived as a key architect of the special economic zone. He has been accused of stealing public funds on projects such as Zhuhai airport.
