Poll: Do you think Richard Scudamore's position as Premier League chief executive is untenable?

The pressure on Premier League chief executive Richard Scudamore over sexist emails today intensified after Football Association chairman Greg Dyke described the remarks as "totally inappropriate".

Scudamore has apologised for the emails, which were sent privately to a friend but were published in a Sunday newspaper.

Dyke said today: "Our policy has always been that we do not consider something stated in a private email communication to amount to professional misconduct. We do, however, consider the content of the emails to be totally inappropriate."

A special meeting of the FA's Inclusion Advisory Board has been convened for next Tuesday by the chair Heather Rabbatts.

Dyke's comments go significantly further than the official FA statement issued on Monday, as does an email to staff from FA general secretary Alex Horne.

Horne said: "It is important I communicate to all staff how disappointed all of us are in the tone and nature of the content of these emails which we believe is totally inappropriate."

"Richard is not an employee of the FA and the matter is one for the Premier League to address considering their respective policies. The issue is something we will continue to monitor."

There is growing concern among some figures both inside and outside the FA at the lack of formal action taken by the Premier League.

Sports minister Helen Grant has already branded the content of Scudamore's emails "completely unacceptable" while Labour's shadow sports minister Clive Efford has written to both the FA and Premier League asking why Scudamore has not faced action.

Scudamore's emails were seen by a former temporary PA who leaked them to the Sunday Mirror. As well as some sexual innuendoes, the email exchanges also made sexist jokes about "female irrationality".

In a statement Scudamore said the exchanges were "private emails exchanged between colleagues and friends of many years" that should not have been accessed by the temporary employee, but accepted they were inappropriate and added: "It was an error of judgment that I will not make again".
