Former Solicitor-General John Les has been interviewed by the RCMP in the investigation into his land deals in Chilliwack, according to the special prosecutor who is overseeing the probe.

Prosecutor Robin McFee wouldn't say what the interview uncovered, if anything, but added that more interviews haven't been ruled out in the case, which prompted Les's resignation in late March.

"My understanding is that as part of the ongoing investigation is that there has been a preliminary interview," McFee told CTV News on Tuesday. "Whether or not that will be the only interview remains to be seen."

Until Tuesday, police and the prosecutor would only say they hadn't interviewed Les about his role, through numbered companies, of the purchase and conversion of land in B.C.'s protected Agricultural Land Reserve into profitable two-acre residential lots.

In at least one case, the developments were approved by city council while John Les was mayor.

McFee would not comment on whether police have gained any information that allowed them to proceed to the step of interviewing Les, deferring to the importance of secrecy in the RCMP investigation.

The RCMP has questioned neighbours and business partners of Les about developments he spearheaded on two sites north of downtown Chilliwack.

When the investigation was made public on March 28, the solicitor-general immediately resigned, but denied wrongdoing.

The Agricultural Land Commission has also launched an investigation into every farmland deal in Chilliwack from 1991 on.

One of the documents that has been forwarded from the city of Chilliwack to the commission has to do with developments on Les's own eight-acre property, which he bought in 2004 after separating it from the rest of the farm.

In another two cases at Rosebank Place and Bell Road in Chilliwack, the owners of properties in the Agricultural Land Reserve -- B.C.'s protected farmland -- had applied and failed to develop cheaper farms into lucrative residential lots.

But in those two cases, John Les purchased the land through numbered companies and the developments easily passed zoning hearings. In both cases one of Les's brothers was connected to the projects, documents and interviews showed.

Les sold the land for hundreds of thousands of dollars. The former solicitor-general has not yet been reached for comment.
