A grandmother has gone head-to-head with fraud probe millionaire Robert Skillen on Scotland Tonight.

Solar panel customer Irene Harris confronted the former boss of Helms during a heated debate on Thursday.

Helms sold the UK government's Green Deal scheme to her and thousands of people across Scotland before going into liquidation.

The 65-year-old told Mr Skillen she had sleepless nights and her health has been damaged after solar panels were installed at her Kilmarnock home.

"You don't regret what happened to me and all these other people who are stressed out their heads because of [this]?" she asked him during the debate.

"You're not listening to what people have gone through with this, it's horrendous."

Mr Skillen's former firm has been the subject of hundreds of complaints and a damning report by charity Citizens Advice Scotland.

A trading standards fraud investigation resulted in a report being sent to the Crown Office, which is under consideration.

The businessman claims that he has done nothing wrong - putting the blame on the UK government - and has offered to hand over his entire £10m fortune if anyone can disprove his claim.
