A former chief executive of the Scottish Premier League has slated the Scottish FA's decision to approve Dave King as a fit and proper owner of Rangers.

Roger Mitchell worked just down the corridor at Hampden from the SFA during his four years at the helm of the SPL.

He quit after Rangers and Celtic vetoed the plans for a dedicated SPL TV channel he had formulated with the other clubs.

And today he took to Twitter to comment on the credentials of controverisal South-African businessman King as the SFA prepares to go to the Court of Session to defend its decision to approve his ownership of the Ibrox outfit.

During a conversation with another Twitter user about King's Rangers takeover, he said: "re King, Rangers will come to regret him. I would have strongly opposed him."

When asked to predict if retail magnate Mike Ashley - the instigator of the court action against the SFA - would succeed in his bid to overturn King's endorsement, Mitchell said: "I wouldn't want him on my back. So yes. How can king be fit and proper after what the judge said about him?"

That was a reference to the South African judge who described King as a "glib and shameless liar". 

King's 2013 conviction in relation to breaching 41 criminal counts of South Africa's Income Tax Act saw him sentenced to a fine totalling 3.28 million South African Rand (£180,000) or face 82 years in prison. He avoided the jail sentence by paying the fine.

Mitchell also touched on King's involvement with the Rangers oldco that went into liquidation in 2012 when he tweeted: "and we [sic] was on the board of oldco. So damaged on every level."  

A representative for King said he did not want to comment on the story.
