A British Conservative party leadership TV debate ground to a halt after the presenter Kate McCann fainted live on-air.

Liz Truss and Rishi Sunak were engaged in a head-to-head debate hosted by Talk TV and The Sun newspaper.

They were sparring over their tax and spending plans and what they would do to address a cost of living crisis when McCann was heard collapsing to the floor 30 minutes into the session.

The British Foreign Secretary Truss was visibly shocked and held her hands to her face as she exclaimed 'Oh my God' and the debate was taken off-air.

TalkTV released a statement on why they took the programme off air.

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.

Both Truss and Sunak later sent messages on Twitter wishing McCann well. Liz Truss said: "Relieved to hear @KateEMcCann is fine. Really sorry that such a good debate had to end. Looking forward to catching up with Kate and the rest of the @The Sun @TalkTV team again soon."

Rishi Sunak said: "Good news that you're already recovering @KateEMcCann It was a great debate and I look forward to getting grilled by you again shortly!"

The programme had been set to be a two-presenter interview with the Political Editor and The Sun's Political Editor Harry Cole, who had to withdraw as he had tested positive for Covid.
