Patisserie Valerie chief executive Paul May has said the group could build a 20-strong estate across Ireland.

The group opened its first Irish site in Belfast’s Donegall Square earlier this year.

May told the Belfast Telegraph the company would launch next in Londonderry as it also prepares to open up its second shop in Belfast - in Castle Lane. He said he was also eyeing up another three sites in the city.

May said: “The first Belfast store has been trading fantastically well and we are excited to expand further into Belfast. We first looked at the site (on Castle Lane) about six weeks ago and are at the drawings and designs stage.

“Because we open a lot of stores we tend to do it fairly quickly - on average we open around three-and-a-half weeks after we sign the lease.

“Because we fitted out our first store with a bakery in the basement we have the capacity to set up to 20 stores in southern and Northern Ireland.”
