Williams has been a major shareholder at Port Vale since February 2006
The businessman hoping to take over at Port Vale has urged pop star Robbie Williams to vote at an Extraordinary General Meeting on 1 June.
Mo Chaudry has made a plea to Williams, who is a major shareholder at Port Vale, not to abstain from voting on the future of the League Two club.
Williams owns 24.9% of shares but has said he would abstain on any EGM vote.
"If Robbie was prepared to invest in Vale he should take responsibility and vote," Chaudry told BBC Radio Stoke.
"Robbie will effectively neutralise the board's vote and then it would be very interesting because we would see proper democracy in play."
Local businessman Chaudry has offered to purchase 51% of shares in the Burslem outfit - worth £1.2m - in an attempt to gain a controlling interest, but club rules state that no one person can own more than 24.9%.
I'll go if shareholders vote me out - Bratt
The Vale board's refusal to accept Chaudry's offer has angered supporters to the extent that a group of fans have organised the EGM.
The North London Valiants sent a questionnaire to the club's shareholders showing that 40% are in favour of calling the meeting.
The current board took charge at Vale Park in December 2003 when the Valiants were in administration.
The fan-backed Valiant 2001, with Bill Bratt installed as chairman, led Vale out of administration a season later, but fans now think it is time for a fresh approach.
"Valiant 2001 was formed to keep the club in the hands of the supporters," said Bratt. "This is why the 24.9% share holding rule was introduced and we still believe that this is the right way to go."
But Vale chairman Bill Bratt says he will accept any decision that the shareholders make.
"If the shareholders vote me out then that is ok with me," said Bratt.
"It could go either way. If we're voted out, we'll go but I'll always support the club.
"At the end of the day, it's not about me, it's about Port Vale and, if they think that that is best for the club, then so be it."
