McLaren’s lucrative title sponsorship could be in doubt.
The Financial Times reports that Vodafone, the British telecommunications national, "is reviewing" its major sponsorship deals.
Vodafone is Woking based McLaren’s naming sponsor and the review "will probably raise questions about its continued involvement", wrote telecoms journalist Daniel Thomas.
The current contract, which according to one source is worth "tens of millions of pounds" a year to McLaren, runs out at the end of next season.
The source added that mobile phone businesses throughout Europe are struggling in the current economy.
Vodafone did not comment, while another source said the review is "informal" and no conclusions have been made yet.
