Barclays Premier League chief executive Richard Scudamore has issued an apology after private emails were published which contained "inappropriate" jokes about women.
The emails were published in a Sunday newspaper after copies were taken by a former personal assistant to the chief executive.
Scudamore said in a statement released by the Premier League: "These were private emails exchanged between colleagues and friends of many years.
"They were received from and sent to my private and confidential email address, which a temporary employee who was with the organisation for only a matter of weeks, should not have accessed and was under no instruction to do so.
"Nonetheless I accept the contents are inappropriate and apologise for any offence caused, particularly to this person.
"It was an error of judgement that I will not make again."
