Buckingham Palace has denied a report that the Duke of Edinburgh has received a diagnosis of prostate cancer.
In a statement, Buckingham Palace said: "The Duke of Edinburgh has authorised us to confirm that the claim made by the Evening Standard that he has received a 'diagnosis of prostate cancer' is untrue."
The London newspaper reported that Philip, 87, was diagnosed with the condition while being treated in a London hospital for a chest infection in April.
The palace statement read: "We believe that the Evening Standard's front page story today titled 'Prince Philip Defies Cancer Scare' is a serious breach of Prince Philip's privacy.
"Buckingham Palace has always maintained that members of the Royal Family have a right to privacy, particularly in relation to their personal health.
"For this reason, we have always refused to confirm or deny the persistent rumours that circulate about their health, particularly during the quieter news months.
"We will continue to observe this long-standing practice; but on this occasion, because the damaging story is now being reported widely, the Duke of Edinburgh has authorised us to confirm that the claim made by the Evening Standard that he has received a 'diagnosis of prostate cancer' is untrue.
"We believe there has been a serious breach of the Duke of Edinburgh's right to privacy and we will be taking this issue to the Press Complaints Commission.
"We will be asking the PCC to remind all editors of their obligations."
