The Rugby Football League are to tighten up their rules after the London Broncos were given the go-ahead to keep playing in Super League.

The club went into liquidation with debts of around �3m but restructured its finances to allow them to continue.

"While London are undoubtedly relieved to have been saved, it cannot be allowed to mask the serious issue raised," said RFL spokesman Nigel Wood.

"I expect the RFL to review its rules and make recommendations."

The Broncos had to rely on a narrow vote at Friday's emergency meeting of Super League clubs to allow them to play on.

Wood added: "Perhaps we can learn something from other sports, particularly as regards the sanctions and penalties that may be available to ensure that defaulting clubs are not seen to have gained a competitive advantage."
