The 200-page Rangers dossier at the heart of the civil war engulfing the Scottish game claims Neil Doncaster suggested Sky could sponsor the Scottish Premiership free of charge.

The revelation is one of the most intriguing of a document sent to the 42 member clubs that the Ibrox giants claims damages the SPFL executive beyond repair.

A Scottish source with sight of the dossier has told Football Insider how the document reveals how CEO Doncaster spoke to Rangers managing director Stewart Robertson about awarding handing league sponsorship rights to Sky to offset the £10million liability to broadcasters for ending the season early.

The SPFL are looking for a new sponsor for next season after Ladbrokes opted not to extend their five-year partnership.

Initially reported by the BBC to be worth in the region of £2m per season, the deal was extended in 2017 and was heralded as the biggest ever in Scottish football.

Rangers’ claim about Sky getting the sponsorship deal for nothing is not quite the ‘smoking gun’ needed to placate critics of their strong attack on the league governing body over the last month.

The club had called for Doncaster and legal adviser Rod McKenzie to be suspended after claiming they had received “alarming” evidence from a whistleblower and further alleging clubs were “bullied” into voting for the SPFL.

After saying they would release the evidence to clubs “well in advance” of next Tuesday’s general meeting, Rangers presented their case at 10am on Thursday morning.

It was quickly met with a strong response from the league.

“An initial examination of their ‘dossier’ has failed to identify a single shred of evidence to support Rangers’ vociferous claims of corruption, bullying and coercion by SPFL staff,” a spokesman said.
