Charles Green has confirmed that talks are continuing with the Scottish Premier League today as his Rangers newco club bids to gain membership of the Scottish Football Association.
Ibrox chief executive Green has no option but to accept the SFA's 12-month transfer embargo that comes with Rangers' membership.
However, issues with the SPL appear to centre on the league's ongoing investigation into alleged undisclosed payments to players, which could see the Govan club stripped of titles.
Green told Rangers' official website: "We have reached agreement with the SFA and SFL (Scottish Football League) on all matters but not with the SPL.
"As a result, talks are continuing to secure our SFA membership which we are hoping to receive today."
The SPL probe was launched in early March and delayed for months by the failure of Rangers' administrators to hand over documents.
Rangers boss Ally McCoist declared he would never accept Rangers being stripped of titles at the weekend and the situation has been further complicated by the financial crisis facing the SPL following the loss of the Ibrox club to the Irn-Bru Third Division.
