Jolyon Palmer to clean track on Friday mornings

(GMM) Lotus has signed reigning GP2 champion Jolyon Palmer as its third and reserve driver for 2015.

The Enstone team said the 24-year-old Briton, whose father Jonathan is a former F1 driver, broadcaster and circuit owner, will attend all the races and take part in "a significant number" of Friday practice sessions.

"My goal has been to become a race driver in a competitive F1 team for 2016 and Lotus is a great opportunity for me, particularly with Mercedes engines now," said Palmer.
