HOCKENHEIM, Germany (Reuters) – Four-times Formula One world champion Lewis Hamilton has signed a new two-year deal keeping him at Mercedes until the end of 2020, the team announced on Thursday.

The 33-year-old Briton would have been out of contract at the end of 2018 and negotiations have been a talking point since last year.
