IN another unprecedented show of Legco solidarity, the Liberal Party endorsed the candidacy of the Democratic Party's Dr Yeung Sum to chair Legco's powerful Finance Committee yesterday. Dr Yeung's nomination was proposed by Liberal Party's James Tien Pei-chun. He was elected uncontested. Dr Yeung denied a deal had been struck with the Liberals in exchange for support of Mr Tien as chairman of the constitutional affairs panel. But Mr Tien said he nominated Dr Yeung in return for their party's support of Ronald Arculli as House Committee deputy and because Dr Yeung had lobbied him. Although Mr Tien said he 'did not necessarily want to be the panel chairman' he would head it if nominated by the Democrats. The Finance Committee chair was believed to have been hotly contested between Dr Yeung and Elizabeth Wong Chien Chi-lin, but Mrs Wong became deputy without challenge. Mrs Wong said she had not attempted to lobby the Democrats for support. Neither were there discussions with Cheung Man-kwong who nominated her for deputy.
