Staveley has secured financial backing from the Middle East as she gears up to negotiate with Tottenham for a potential minority stake in the club, according to sources.
It's been suggested Staveley's initial purchase will be used to buy further into the club.
A bid for a 25 per cent stake in Spurs has been mooted to the tune of £650m.
Staveley still has a 9.9 per cent stake in Newcastle, which is below the threshold of preventing individuals from having stakes in multiple Premier League clubs.
