Iris Robinson, wife of Northern Ireland's First Minster Peter Robinson has been questioned by the Police Service of Northern Ireland (PSNI) into her financial dealings after it emerged that she may have accepted substantial donations from two developers.

The disgraced former MP had to resign this January after it emerged that she’d had an affair with a 19-year-old teenager; the news shocked Northern Ireland.

Now it has emerged that Robinson  was questioned in London after BBC’s Spotlight programme made allegations that Mrs. Robinson had obtained £50,000 from two developers in order to fund her young lover’s ambitions to start a restaurant.

The ex-politician was reportedly interviewed by two detectives in the presence of a solicitor, but the tape recorder malfunctioned, apparently rendering the interview worthless.

Mrs Robinson revealed that she had gone into clinical depression after the revelation of the shock affair emerged and that she had attempted suicide.

After news of the affair broke, Peter Robinson invited four journalists to his home to give his own agonized account of his family's private turmoil – an unprecedented display from a man renowned for an icy demeanor

Robinson’s ex-lover, Kirk McCambley, is now 21. "She looked out for me to make sure I was OK," the young man said of the relationship.

The PSNI refused comment: “We do not comment on named individuals. Neither do we discuss our investigative process."
