Video has emerged of the moment a man took Simon Holmes A Court, the man behind Climate 200, to task at an event.

Barclay McGain interrupted the event to question the lack of discussion surrounding how renewables would lower power bills.

He told 4BC Drive host Gary Hardgrave he believes the audience needed to know they were being sucked into a con.

“I think it’s something that Simon Holmes A Court owes the rest of the room,” he said.
