John Greig and John McClelland have resigned as non-executive directors of Rangers Football Club PLC.
The news was confirmed via a statement released on Monday which claimed they have been isolated following Craig Whyte's takeover of the Ibrox club in May.
"These resignations have been communicated by letter to the chairman, Craig Whyte,'' the statement read.
"They result from John McClelland and John Greig both being of the opinion that since the change of ownership they have been excluded from participating in corporate governance at the club.
"Therefore they have decided not to continue in their positions as non-executive directors.''
The resignations come just one week after Rangers finance director Donald McIntyre also stepped down from the board.
McIntyre and former chief executive Martin Bain were both suspended by the Scottish champions in May, shortly after Whyte completed his takeover.
McClelland and Greig survived that initial overhaul of the Ibrox boardroom, but their decisions to step down on Monday add to a growing list of off-field problems for Rangers.
The Scottish champions, who lead Motherwell by seven points at the top of the SPL, are currently involved in two separate tax disputes with HM Revenue and Customs, while Bain is also suing the club for £1.3 million in an unfair dismissal claim.
Greig captained Rangers during his playing days there in the 1960s and 1970s, leading them to victory in the final of the European Cup Winners Cup in 1972. McClelland was chairman of the club between 2002 and 2004.
