Paris 2024 chief Tony Estanguet says the Games will protected by an “unprecedented” security operation, and that preparations are “in good shape”.

But with 100 days until the start of the Olympics, he said organisers will “keep some humility, because we know in this kind of event anything can happen in the last stretch”.

Estanguet added he was “very satisfied with where we stand at this moment”.

He told BBC Sport: “My message is you can have confidence with this event.”

Amid mounting concerns over safety, Estanguet said “I would like to reassure that it’s non-negotiable. Security is the priority.”

“It’s the biggest event that France has ever organised, and we want to showcase the best of France. So definitely we are determined to be ready.

“We are looking forward to welcoming the world in Paris.”

“When I discussed this with [London 2012 chief] Seb Coe, he told me…in the last 100 days, there will be more criticism, more people worried. It’s exactly what is happening. My role is to remain calm, remain focused on what is very important to deliver.

“The venues are ready, the budget is balanced. We have very good ticket sales, the level of ambition is very high.”
