LONDON (Reuters) - Poland's former grand prix winner Robert Kubica will be the reserve and development driver for Williams this season, the Formula One team said on Tuesday.


Russian Sergey Sirotkin was earlier announced as a race driver for the former champions, partnering Canadian Lance Stroll.


Kubica, 33, had been hoping to get the race seat and return to the starting grid for the first time since a 2011 rally accident partially severed his right arm.
