Sir Frank Williams is to step down from the board of the F1 team that carries his name.

The 69-year-old, who will remain in the position of team principal, has taken the decision as he begins the process of handing over the reins of the team 'to the next generation'.

At the same time, Claire Williams will join the board from 1 April as director of marketing and communications, with the position having been made available after Dominic Reilly decided to leave the team at the end of March.

"It is no secret that Claire is my daughter but I am proud to say that she has fought hard to earn this appointment and of all the battles she has had to fight, the prejudices of her father were not the least challenging," Frank Williams said. "Dominic Reilly has proven a unique talent in the field of sports marketing and filling the gap he leaves was daunting. But I have come to the view that Claire, with her profound love and knowledge of the sport and the team, can do so and I am proud and delighted that the Board has given her this opportunity. I am equally delighted that Dominic will remain close to the team with his new venture and that we can thank him for his contribution to Williams by supporting him now.

"This is an opportune moment, also, for me to consider my own role in the team. I turn 70 in April and I have decided to signal the next stage in the gradual but inevitable process of handing over the reins to the next generation by stepping down from the Board at the end of this month. This is not as dramatic a move as it may appear: I shall continue to work full-time as Team Principal and I shall continue to attend all Board meetings as observer. I also remain the majority shareholder of Williams Grand Prix Holdings PLC.

"Nonetheless, I shall be looking to Claire to represent the Williams family on the Board and I know that she will work tirelessly alongside Adam to make the Group and the team just as successful as we can be."

Williams' decision to leave the board comes after co-founder Patrick Head also stood down last year.
