When court opened this morning the judge addressed the jury and told them that the current witness, former News of the World editor Clive Goodman, was unwell.
He had been seen by the court matron, Judge Saunders said, and after examining the defendant she had called an ambulance to take him to hospital. The court has already heard that Goodman has recently undergone one operation for a heart problem and another to remove a cataract.
Judge Saunders then adjourned proceedings until Monday.
All of the defendants deny all of the charges, the trial continues.
