The annual list of F1 salaries has again been published, and while Fernando Alonso remains top, he has now been joined by Lewis Hamilton.

The report - published by Spanish newspaper El Mundo Deportivo and citing information compiled by Business Book GP - reckons both are now on around EUR20 million, Hamilton getting an extra EUR4 million per year following his switch from McLaren to Mercedes.

Interestingly though, the same publication had Alonso on a retainer of EUR30 million in 2012 - it is unclear why this estimate for the Ferrari #1 has now been revised...

Jenson Button meanwhile remains third, taking home EUR16 million, while triple F1 world champion, Sebastian Vettel has got an increase and now earns EUR12 million with Red Bull, EUR1 million a year more than Nico Rosberg and EUR2 million a year more than Mark Webber.

Felipe Massa has had a pay cut, reduced from EUR10 million a year to EUR6 million, while Kimi Raikkonen seems to be a relative bargain for Lotus on only EUR3 million a year (EUR2 million less than the figure quoted in 2012), although it is rumoured his pot is boosted substantially according to how he performs and how many points he scores.

Further back, Sergio Perez is now earning three times more than last year following his move to McLaren, with the Woking-based team paying him EUR1.5 million a season. Romain Grosjean, Nico Hulkenberg and Pastor Maldonado are the only other drivers said to be in the EUR1 million a year bracket, with Valtteri Bottas on EUR600,000, ahead of Jules Bianchi and Adrian Sutil on EUR500,000 apiece.
