Lady Nina Bracewell-Smith says she has no plans of selling her shares in Arsenal.
She is sitting on a £100million fortune, potentially a key player in the takeover strategy of 'Silent' Stan Kroenke.
Her 15.9 per cent stake is a stumbling block, a considerable barrier to Kroenke's aspirations of owning Arsenal lock, stock and barrel.
Kroenke has reached the threshold, upping his stake in the Gunners to 29.9 per cent and threatening to take the club into American hands.
Lady Nina told the News of the World: "It is all so delicate but selling my shares is not something I want to do at the moment. No one has offered to buy them.
"What is important right now is the team. Everyone has to concentrate on what is happening on the pitch.
"I don't want to be controversial but I don't know what I'm going to do with my shareholding just yet."
