Swansea City Supporters' Trust has called for the exit of club chairman Huw Jenkins amid an ongoing dispute over the sale of the club in 2016, BBC Sport have reported.
The Trust has claimed that it was excluded from preliminary negotiations despite having a 21.1% stake in the club.
"For people to... say they didn't know about the sale annoys me because it's wrong," said Jenkins on Friday.
Co-owner Jason Levien has claimed that talks started in 2015, but the Trust were not alerted until the following year.
A consortium headed by Levien and fellow American Steve Kaplan bought a controlling stake of 68% in Swansea City in July 2016.
