The Football Association has appointed Alex Horne as acting chief executive following Ian Watmore's resignation.

Watmore resigned on Monday after just nine months in the role, with the FA declining to go into detail about why he decided to walk away from the job.

Meanwhile, chairman Lord Triesman has revealed that no permanent appointment will be made until the end of the year following an emergency meeting of the FA's board at Wembley on Tuesday afternoon.

"The board have invited current chief operating officer Alex Horne to take on the role of acting chief executive officer with immediate effect," read an FA statement.

"The board regrets that Ian has decided not to continue as CEO, but has every confidence in Alex, the outstanding staff at the FA and the managerial leadership in place within the organisation.

"It has been agreed that Ian Watmore will leave the organisation at the end of this month."
