Richard Scudamore's tenure as the Premier League's chief executive is under increasing threat after the league's main sponsor Barclays expressed concerns over his sexist emails and a equality campaigner called for him to go.
Edward Lord, who is also a member of the Football Association's inclusion advisory board (IAB), wrote on his personal blog that Scudamore's position is now "untenable".
It is understood that Barclays expressed disappointment to the league this week about the content of emails Scudamore sent to a lawyer friend, which were revealed by the Sunday Mirror last weekend.
The Premier League is set to meet on Monday to discuss the case, which will also discussed at a special meeting of the IAB on Tuesday.
