LONDON (Reuters) - Brazilian driver Felipe Massa announced his retirement from Formula One at the end of the season, and for the second time, on Saturday.
The 36-year-old had been due to retire last season but was recalled by the Williams team after Valtteri Bottas left for Mercedes following the surprise retirement of 2016 world champion Nico Rosberg.
