London yoga studio, Triyoga, is at the centre of a neighbourhood row involving allegations of noise during several classes. The complaints focus on a mother and baby session during which nursery rymes are sung, and a preganancy class where music is played.
Camden council issued an enforcement notice at the end of January which Triyoga has a month to respond to, and which could result in a fine.
Jonathan Sattin, managing director of Triyoga, denied that the centre faces closure.
He said: "When the council first rang me up I thought they were joking. I am astonished that anyone would take issue with mothers singing nursery rhymes to their children for six minutes in the middle of the day."
Triyoga, in Primrose Hill, is London's most fashionable yoga centre, and is known for its celebrity cache; Gwyneth Paltrow, Jools Oliver and Sadie Frost are all regulars.
