Iris Robinson was 59 when the affair began.

Iris Robinson is currently under investigation by the Police Service Northern Ireland (PSNI) after it was reported that she had received $80,000 from two developers to fund her teenage lover's business venture.

The PSNI have confirmed that the organized crime branch, under the direction of Detective Chief Superintendent Roy McComb, will lead the investigation. There is a possibility that Robinson could be slapped with charges of corruption.

The PSNI released a statement saying: "The investigation will be conducted in a thorough and professional manner as expeditiously as possible. It will also be conducted with respect to the human rights of any person and in a manner that complies with the Police Service’s duty to carry out impartial and independent investigations in compliance with our Code of Ethics."

Robinson was forced to resign as an MP for Stangford after it emerged that she had an affair with then 19-year-old Kirk McCambley in 2008.

Robinson was given $40,000 each from developers, Fred Fraser and Kenny Campbell. The money was then used by McCambley to establish his restaurant business called the Lock Keeper's Inn in South Belfast. She reportedly kept $7,000 for herself.

Last month Robinson was forced to resign as an MP and member of her husband's Democratic Unionist Party (DUP). It transpired that Robinson attempted suicide last March after she admitted the affair to her husband.

It has also emerged that she strongly lobbied for several planning applications on behalf of two other property developers.

It has also transpired that Campbell donated $7,000 to the DUP.

Iris is married to Peter Robinson, who is leader of the DUP and has currently stepped down temporarily as the First Minister of Northern Ireland. He is currently under investigation by Stormont’s ethics committee to determine if he broke his ministerial code of conduct.
