Boss goes undercover to see why chips are down

Ms Simovic changes her name and dons an elaborate disguise to discover what really happens in her restaurants as new trainee recruit "Millie Percy".

The 39-year-old is the only female featured in Channel 4 Undercover

Boss series and viewers will see an emotional conclusion to the programme as she reveals her true identity to shocked staff and rewards the unsung heroes she encounters.

Ms Simovic said: "Harry's is a British institution and I'm determined to put it back on the map.

"It was nerve-wracking going undercover but the whole experience has really opened my eyes to exactly what needs to be done.

"It's not going to be easy. But what impressed me the most was our wonderful workforce, many of whom have been with Harry's for decades."

It is the second series of Undercover Boss, and other programmes will feature senior staff from the Best Western hotel chain as well as the Jockey Club, the largest commercial organisation in British horseracing.

Founded in 1928, there are currently 34 restaurants and takeaways within the Harry Ramsden business including the largest fish and chip shop in the world in Guiseley near Leeds.

The new owner, a West Midlands-based food entrepreneur, has plans for 100 more stores in the UK as well as taking British fish and chips to India and China.

The business was started by Harry Ramsden in a wooden hut in Guiseley, which still stands on the same site adjacent to the main restaurant which holds the Guinness World Record for the largest fish and chip shop in the world, seating 250 people, and serving nearly a million customers a year.
