LONDON, July 16 (Reuters) - Ocado, the British online supermarket and technology group, said investors should not be losing confidence despite a slowdown in the rollout of robotic sites and modules for its retail partners.

"I'm not concerned in investors losing confidence, because they shouldn't be losing confidence. We've got a clear plan and we're executing to that clear plan," Chief Executive Tim Steiner told Reuters on Tuesday. (Reporting by James Davey, writing by Sarah Young; Editing by Sachin Ravikumar)
