The proposed changes involve the number of teams in the SPL staying at 12, with a second and third division containing 12 and 18 teams respectively.

The new structure could be in place for the start of the next season, if it can be ratified and organised in time.

SPL chief executive Neil Doncaster was pleased with the discussions, describing them as 'robust but positive'.

"The clubs were united in their view about the need for change," he said.

"I firmly believe that any change can only come from consensus and there's one consensus model for change going forward.

"The SPL clubs have been clear today that they, in principle, back this being taken to the next stage."

As things stand there are three divisions below the SPL, each of which contains 10 teams.

Following the SPL clubs' ratification of the proposal, the 30 Scottish Football League clubs will now vote on the change on Thursday.

Scottish Football League executive David Longmuir has warned that time constraints could hinder the league structure being introduced by next season.

"In terms of a voting meeting, 21 days are required but the notice period can be reduced through mutual agreement," Longmuir said.

"I'm not giving any view either way on whether it's feasible for next season. I think it would be very tight but we'll see what comes from (the SPL meeting) first of all and then we'll take it from there."
