Home Affairs Select Committee chairman Keith Vaz wrote to Rupert Murdoch asking him to comment on the secret recording.
In a reply released today, Mr Murdoch said:
I accept that I used the wrong adjectives to voice my frustration over the course of the police investigation.
But I had been hearing for months about pre-dawn raids undertaken by as many as 14 police officers, and that some employees and their families were left in limbo for as much as a year and a half between arrest and charging decisions.
I have no basis to question the competence of the police and I and our newspapers respect the work that they do every day to protect the public.
But I do question whether, over the last two years, the police have approached these matters with an appropriate sense of proportion, and with regard for the human cost of delay.
