Monaco Grand Prix 2012: McLaren set to offer Lewis Hamilton a new £20m contract It may be that a lower basic salary is accepted which would allow Hamilton more control of this area. It is understood that Simon Fuller, XIX's chief executive, will be in London in July and August - hoping, amongst other things, to watch his other star clients David Beckham and Andy Murrary compete at the Olympics - and negotiations are likely to pick up pace at that point. With potential vacancies next year at Ferrari and Red Bull, and possibly Mercedes too, there is always the chance that one of McLaren's rivals may make a play for Hamilton or that he could try to engineer a move if he felt they were more likely to give him a winning car. Hamilton's team mate Jenson Button went fastest yesterday in practice for Sunday's Monaco Grand Prix but intermittent rain made it difficult to judge relative pace. Meanwhile, Lotus have said they will not allow Kimi Raikkonen to take part in Rally Finland later this summer following their experience with Robert Kubica last year. The Pole's career is on hold following a major crash in a pre-season rally and Raikkonen's contract forbids him from taking part in similar extra-curricular activities. The 2007 world champion had sought clearance to make a one-off return to the WRC but was told it would not be possible.
