“Kate McCann fainted on air tonight and although she is fine, the medical advice was that we shouldn’t continue with the debate. We apologise to our viewers and listeners,” a spokesperson said.

As Rishi Sunak and Liz Truss were clashing once again over taxes, NHS funding and the economy in their second head-to-head televised debate, a loud crash interrupted the two Tory rivals.

The British Foreign Secretary looked visibly worried and could be heard saying “oh my god”, as she walked off the stage.

The programme immediately went off-air, with a message appearing on the screen, saying: “We are sorry for the disruption to this programme.

“We are working hard to fix the issue and will return to normal programming soon.”

A Sun spokeswoman said the debate was paused because of a medical issue.

“There was a medical issue, we hope to be back on air soon,” she said.

It is understood the debate’s host, TalkTV’s political editor Kate McCann, fainted during the debate.

Ms McCann was meant to appear alongside The Sun’s political editor Harry Cole, but he tested positive for Covid-19 earlier today.
