The Green camp

l Ex-chief executive Charles Green: The former Sheffield United chief executive led the consortium that bought Rangers after administration and liquidation. He quit the post in April amid claims he was linked to former owner Craig Whyte but returned last week to advise on financial matters.

l Finance director Brian Stockbridge: Brought in under Mr Green and understood to be close to former director Imran Ahmad. It was suggested he was behind a video which showed former chairman Malcolm Murray apparently behaving drunkenly at a restaurant this year.

l Ex-commercial director Imran Ahmad: He recruited Mr Green to front the consortium, from Zeus Capital, a finance firm, but was axed from the club in April amid a row over anonymous postings on a website which criticised Ally McCoist and Walter Smith.

l Also in the Green corner is non-executive [independent] director Bryan Smart, a former Mercedes-Benz UK director.

The opposing camp

l Jim McColl: Owner of Clyde Blowers, which has an estimated turnover of £1.35 billion. His personal wealth has been put at £1bn and he was number five in the Sunday Times Scotland Rich List. He is attempting to force a boardroom clearout and install former director Paul Murray and Frank Blin. Claims he is not planning a takeover.

l Paul Murray: Appointed to the Rangers board in 2007 and resigned in 2011 when Craig Whyte assumed control. He led the failed Blue Knights bid to take over the club last year. Among a group of shareholders who have demanded an extraordinary general meeting.

l Frank Blin: Former executive chairman of accountancy firm Pricewaterhouse­Coopers Scotland. The group of shareholders, including McColl, want him on the board to forensically examine the club's finances.

l Former chairman Walter Smith: The former Rangers manager, who led a consortium that tried to buy the club from Green last year before it withdrew, issued a damning resignation statement on Monday night describing the board as "highly dysfunctional" and lacking integrity.

In the middle

l Rangers chief executive Craig Mather: Invested £1million after Charles Green's consortium bought the club, and has worked hard to gain the trust of Ally McCoist and Walter Smith. In his resignation as chairman on Monday, Smith said Mr Mather was doing a good job and should continue.
