Christian Verhounig, the line’s chief executive, said Lupino was "an essential member of the team" which launched the company and a "long-term friend".

“In these moments, the overriding feeling is one of utter shock, disbelief and sadness, but I hope in time the sadness will make way to gratitude – gratitude for what a fantastic, vibrant character and valued colleague, business partner and friend Michelle has been to us all," Verhounig added.

"Her extreme dedication, attention to detail and creativity have played a big part in us being where we are today, and she will be greatly missed by all at Ambassador and her many friends in the industry."

The company has extended its condolences to Lupino’s family and friends. "We understand how distressing the news of Michelle’s passing is to the Ambassador team, for whom she was a respected and much-loved colleague," Verhounig added.

 
Lupino had made it known she did not wish for flowers to be sent to mark her passing. Accordingly, her family have set up a JustGiving page you can access here in her memory, with all donations going to the RSPCA.
