Sir Philip Green has unveiled details of his long-awaited Topshop flagship store in New York and said he plans to open up to 15 US flagships.

Green said he wanted to have between 12 and 15 flagships in cities such as Miami, Los Angeles and Las Vegas. He said he was also looking at Canada for possible store locations.

The US$20m (£14m) New York store will house exclusive collections from US designers and will have a no-Sale policy. Green said: “Not everybody wants to be in the $2 range,” saying that product would be key and that it was in America for “the long haul”.

Green also explained the delays, which moved the date to this year, when it had initially planned to open last autumn. “Floods, fire, everything possible has happened to us,” he said.

He also said that despite difficult trading hitting many retailers his businesses “are still in positive territory". He also said that in the UK Topshop’s post-Christmas Sale had been the biggest in its history.

Supermodel Kate Moss will be at the opening of the store on April 2. Moss is currently working on a lingerie range to run alongside her fashion range for Topshop.
