Lewis Hamilton has ended his four-year relationship with management company XIX Entertainment.
The Mercedes driver, who currently leads the F1 world championship standings by 17 points, signed for Simon Fuller's group at the start of 2011.
However, upon the conclusion of the contract, Hamilton has opted to search for new management.
When asked bout the parting of ways, he is quoted by the Daily Mail as saying: "There is not really much to say. The contract expired and I am going to be doing something different. I don't know what yet, but I will decide at the end of the year."
Fuller played a key role in Hamilton's contract negotiations when he made the move from McLaren to Mercedes in 2012.
