Mr Gilligan’s home was searched by police last month The chairman of the NI Policing Board is to seek its members’ support to remain in the role at a meeting later.
Last month, Barry Gilligan went voluntarily to a police station to be interviewed about a land deal involving a company, of which he is a director.
It followed a police search of Mr Gilligan’s home and the headquarters of the Policing Board.
The land in question at Nelson Street in north Belfast had been designated for social housing.
The controversy began when it emerged that Mr Gilligan had been asked to offer advice to a community group which wanted to build social housing on the site.
But, within weeks, Big Picture Developments, of which Mr Gilligan is a director, acquired the site, collapsing the community group’s plans.
Mr Gilligan, who is on leave from his Policing Board post because of health problems, denies any wrongdoing.
In March, the Housing Executive asked police to investigate its involvement with the Nelson Street site.
For years, the Housing Executive opposed the commercial scheme, insisting the land was designated for social housing.
However, an investigation by the BBC Newsline programme showed that the Housing Executive subsequently appeared to change its mind, with one official writing to planners telling them that it was “withdrawing the request for social housing at the scheme”.
It is believed this letter is the focus of the police investigation.
After it was discovered, senior staff at the Housing Executive ensured the letter was withdrawn and its original position of opposition to the development was reinstated.
