A mother and son have been charged over a burglary at the home of Tamara Ecclestone.
Jewellery believed to be valued at £50m was stolen from the heiress’s home next to London’s Hyde Park in December.
Maria Mester, 47, of no fixed abode, and 29-year-old Emil-Bogdan Savastru, of Bethnal Green, have been charged with conspiracy to commit burglary.
The cleaner and her bar worker son both appeared at Westminster Magistrates’ Court on Saturday.
They will next appear in custody at Isleworth Crown Court on 28 February.
Rings, earrings and an £80,000 Cartier bangle were all stolen in the burglary, according to The Sun.
The court heard the majority of the items taken have not been recovered.
Two men, aged 21 and 31, who were also arrested have been released under investigation, police said.
The burglary on 13 December occurred just after Ms Ecclestone, the daughter of ex-Formula 1 boss Bernie Ecclestone, left the country with her husband Jay Rutland and their daughter Sophia.
The raiders are believed to have entered through a garden before breaking into safes hidden in the bedroom of the 55-room house in Palace Green, Kensington.
