If there is a mood for change, the SPL may move quickly to set up talks with the Scottish Football League.

A Scottish Football Association arbitration panel recently concluded such an expansion would not breach a prior agreement between the SPL and the SFL.

But the SFL challenged the idea, insisting it would break a settlement deal which was reached when the SPL was first set up in 1998.
