GLASGOW'S Charles Rennie Mackintosh inspired Willow Tea Rooms are up for sale, it has been confirmed.

The owner of the business, Anne Mulhern, has put the business on the market after 36 years trading.

It is understood the 63-year-old decided to sell after a period of ill health earlier this year.

The venue's interior is inspired by Mackintosh's design for Kate Cranston’s Ingram Street Tea Rooms.

New owners will be asked to submit offers over £125,000, which includes the trade fixtures, fittings, furnishings, equipment and The Willow Tea Room’s brand.

Rent for the building is listed at £65,000 per annum by leasing agent CDLH, who said annual sales are more than £1million.

The Willow Tea Rooms within the Watt Brothers Department Store on Sauchiehall Street will form part of the sale discussions.

A spokeswoman for the Willow Tea Rooms said: "Anne had a bit of ill health earlier this year and has decided the time has come to the put the business on the market.

"In many respects it has never looked better, we have a new Jo Malone store right next door. It's a great business and the staff are fantastic.

"Anne will be remaining until a new owner can be found but at the moment, it's business as usual."

Alan Creevy, director at leasing agent CDLH, said: "This is a unique opportunity to acquire highly profitable business with sales over £1 million pa, which will undoubtedly be of interest to existing operators, as well as those simply wishing to enjoy the ownership of a much-loved Glasgow institution."

The original tea rooms site was chosen because it was in the middle of Glasgow’s most fashionable street - ‘Sauchiehall’ means ‘alley of willows’
