Rafiq and senior Yorkshire executives have been called to give evidence before a parliamentary Digital, Culture, Media and Sport (DCMS) panel on November 16
Yorkshire County Cricket Club chairman Roger Hutton has resigned with immediate effect following the club's handling of allegations of racism by former player Azeem Rafiq, the BBC reported on Friday.
Rafiq, a player of Pakistani descent and a former captain of the England Under-19s, said last year he was made to feel like an outsider at Yorkshire and contemplated taking his own life.
"There has been constant unwillingness from the executive members of the (Yorkshire) board and senior management at the club to apologise and to accept racism and to look forward," Hutton wrote in his resignation letter.
"For much of my time at the club, I experienced a culture that refuses to accept change or challenge."
Hutton, who joined the board 18 months after Rafiq left the club, also took the opportunity to "apologise unreservedly" to the 30-year-old.
"The club should have recognised at the time the serious allegations of racism," he said.
"I am sorry that we could not persuade executive members of the board to recognise the gravity of the situation and show care and contrition."
England's cricket board (ECB) on Thursday suspended Yorkshire from hosting international or major matches but Hutton said the ECB had also been reluctant to act when approached.
"I want to be clear that when I was made aware of Azeem Rafiq's allegations, I immediately reached out to the ECB to ask for their help and intervention to support a robust inquiry," Hutton said.
"I was saddened when they declined to help as I felt it was a matter of great importance for the game as a whole. It is a matter of record that I have continually expressed my frustration at the ECB's reluctance to act.
The ECB had said it would hold Yorkshire to account over their handling of the matter and consider sanctions. Reuters has contacted the ECB for comment.
