Iris Robinson, the former Northern Ireland MP who had an affair with a 19-year-old, has been questioned by police investigating her financial affairs.

Mrs Robinson, 60, has reportedly been living in London since the scandal of her affair with Kirk McCambley, now 21, broke in January.

She resigned from politics, quitting her seat in Strangford and her place on the Northern Ireland Assembly, and was thought to be receiving psychiatric care.

She was reportedly questioned earlier this month by detectives who asked her how she had persuaded two property developers to loan her £50,000 to help Mr McCambley set up a restaurant on the banks of the River Lagan in South Belfast.

Mrs Robinson tried to kill herself after admitting the affair to her husband Peter Robinson, Northern Ireland’s first minister.

He has denied any knowledge of her alleged financial affairs and insisted he was not questioned by police.

According to AFP sources, a report on the investigation into Mrs Robinson is being prepared and will be sent to the public prosecution service.

Police in Belfast refused to comment on the inquiry.

A spokesman said: ”We do not comment on named individuals. Neither do we discuss our investigative process.”

Deeply religious Mrs Robinson was seen as a hypocrite for her affair with Mr McCambley, who was young enough to be her grandson, because of her homophobic views.

In the past three years, she has called homosexuality an “abomination”, compared to it to paedophilia and suggested gays and lesbians can be “cured”.
