“It seemed sensible as the largest Newcastle United member organisation (and the only one recognised by the Premier League) that we try and speak to Amanda Staveley to see what the Trust could do in this regard,” said NUST.
"Our chair spoke to Amanda by phone, who reiterated how upset both her and the other buyers were about the Premier League's lack of decision, and that Mike Ashley was still very keen to sell her consortium the club.
"In terms of what we could do as a Trust, answers from the Premier League are crucial at this point both for the fans of Newcastle United and the consortium buying the club.
"The Trust already had plans to reach out to the Premier League, both directly and through the Football Supporters Association.
"This is still very much the plan, but in order to harness member feedback beyond the hundreds of excellent emails that have been sent to us, we will aim to have an open forum online in the coming days to understand how best to proceed.”
