Adele has cancelled two more dates of her current UK tour due to illness.
The London-born songwriter had previously cancelled two dates earlier this week, as well as a planned performance at last night's Mercury Prize ceremony.
Her label XL Recordings stated: "She had cancelled her performance at The Mercury Awards last night in the hope she would be able to continue her live dates, but has been told by her doctors that she is still not well enough to perform.
"The shows will be rescheduled at the earliest opportunity and all original tickets will remain valid. Refunds will be available from the point of purchase."
Adele apologised to fans on her official blog earlier today, saying that her illness leaves her "breathless", making it "hard to hold any of [her] notes".
