New anti-graft agency head Simon Peh Yun-lu has rejected claims of a conflict of interest with Chief Executive Leung Chun-ying - the man who appointed him and the possible target of an investigation over illegal structures at his home on The Peak.
The new commissioner of the Independent Commission Against Corruption said his relationship with Leung was strictly professional.
'Mr Tsang is my former boss and Mr Leung is my current boss,' he said. 'Our relationship is a boss-and-subordinate relationship. We do not have any private friendship.'
The Democratic Party and League of Social Democrats have filed complaints with the ICAC, accusing Leung of making false claims during the March election that there were no illegal structures at the property.
It was revealed later that there were six such structures.
While Peh would not comment on progress in the investigation, he stressed that whoever appointed him had no bearing on the case, as the ICAC treated all suspects equally and every case fairly.
