CHART-topping star Paolo Nutini has pulled a further two UK arena shows as he battles "severe tonsilitis".

The 27-year-old musician has postponed tomorrow's performance at the O2 Arena in London, as well as Friday's gig at the Motorpoint Arena in Cardiff as a result of his illness.

Nutini - who topped the charts with third album Caustic Love earlier this year - had already shelved two concerts in his native Glasgow this week on medical advice.

A statement announcing the latest postponements said: "Regrettably Paolo Nutini is suffering with severe tonsillitis and is not well enough to perform."

It also offered an apology for the "inconvenience and disappointment" caused.
