A leaked report compiled by former Football Association (FA) chief executive Ian Watmore has warned that more clubs may be on the verge of financial difficulties.

According to the document seen by BBC Radio 4's The Report programme, Watmore wrote the report before resigning from the FA and suggested more clubs could be facing ruin. Efforts to introduce increased scrutiny over clubs' financial affairs have reportedly been met with opposition from both the Premier League and the Football League.

An FA source told the programme: "The Premier League did not need the FA interfering with the financial side. It saw its role as the financial governing body of the top end of football." However, the FA responded by saying that there was "no evidence" that either competition had opposed plans to introduce new checks that aim to increase clubs' financial security.

It comes as administrators at Portsmouth Football Club revealed the club's debt had increased to £135m as creditors met to discuss new repayment proposals through a Company Voluntary Arrangement. Image: Ben Hardinge/Flickr
