A cleaner has denied plotting to steal £50m in jewellery and cash in a raid on Tamara Ecclestone’s London home.

Maria Mester, 47, pleaded not guilty to conspiracy to commit burglary and a charge of concealing criminal property when she appeared via videolink at Isleworth Crown Court in west London.

The alleged conspiracy is said to have taken place between 30 November 2019 and 1 February 2020, while the concealing criminal property charge dates back to 31 January.

It follows a raid on the home of Ms Ecclestone in Palace Green, Kensington, in west London, on 13 December.

A £300,000 pair of diamond earrings and a Louis Vuitton bag were among the haul which included currency, jewellery and watches with a combined estimated worth of £50m. The majority of it has not been recovered.

The burglary happened just after Ms Ecclestone, the daughter of former Formula One boss Bernie Ecclestone, left the country for her Christmas holiday with her husband Jay Rutland and their daughter Sophia.

Police said in December they were called to the scene by security at the building, which is next to Hyde Park.

Mester, a Romanian cleaner and housemaid of no fixed abode in the UK, was told she will face trial at Isleworth Crown Court on 20 July.

Mester’s bar worker son Emil-Bogdan Savastru, 29, of Bethnal Green, is also charged with conspiracy to commit burglary – as well as having custody or control of a counterfeit currency note and attempting to remove criminal property.
