LONDON (Reuters) - Jessica Ennis-Hill will have doubts about Russian athletes even if they are cleared to compete at the 2016 Rio Games, the Olympic and world heptathlon champion said on Thursday.

Russia were banned from the sport in November following the first part of a World Anti-Doping Agency (WADA) report that found a "deeply rooted culture of cheating" in track and field in the country.
