Formula 1 championship leader Lewis Hamilton will change managers next year, after deciding not to renew his deal with Simon Fuller's XIX Management company.
Hamilton confirmed on Saturday that discussions with Mercedes over a fresh deal beyond 2015 would likely be handled by somebody else.
When asked about the situation, Hamilton said: "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."
Hamilton signed up with XIX management at the start of 2011, having previously had his career looked after by his father Anthony.
XIX played a key part in helping secure Hamilton's move to Mercedes at the start of 2013. His current deal with the team runs until the end of next year.
