Karl Oyston has been replaced as chairman of Blackpool Football Club by recently-appointed director Natalie Christopher..
He has today been terminated as a director of the family-run club, fueling rumours of a feud with his father Owen.
Papers filed with Companies House show Karl Oyston is no longer listed among the directors of Blackpool Football Club Ltd or Blackpool Football Club (Properties) Ltd, which owns the club's Bloomfield Road stadium.
The news comes just over a week after Karl left his director role at another 11 Oyston-run businesses.
A statement issued this evening by Blackpool FC said: "Natalie Christopher has been appointed the new Chairwoman of Blackpool Football Club.
"Mr Karl Oyston is no longer Chairman or Director of the club, or any other Oyston Group company.
"The club will make no further comment at this time."
It was not immediately clear if Karl Oyston left voluntarily or was forced out.
The changes at Blackpool Football Club Ltd leave Owen Oyston, new chairwoman Natalie Christopher - who was appointed as a director on January 17 - Vicki Oyston and Kaspars Varpins as directors. Owen Oyston is now the sole listed director of Blackpool Football Club (Properties) Ltd, according to Companies House.
It follows rumours that Owen and Karl are said to be at loggerheads over the future direction of Blackpool Football Club.
It is understood relations have completely broken down between the two, with Owen wanting to keep control of the club while Karl was reportedly prepared to wash his hands of it.
