The charge relates to burglaries including a raid on Ms Ecclestone’s London home in December 2019 in which thieves allegedly stole £25 million of jewellery and cash.
Ms Ecclestone, the daughter of ex-Formula 1 supremo Bernie Ecclestone, was on holiday in Lapland with her husband, art gallery owner Jay Rutland, their daughter and their dog at the time.
Other alleged victims of the conspiracy included former Chelsea FC player and manager Frank Lampard and his television presenter wife Christine, as well as late Leicester City owner Vichai Srivaddhanaprabha.
Maltese was charged with the conspiracy alongside Alessandro Donati, 43, who pleaded guilty on April 13 and was remanded in custody.
Both men originally denied the charge before entering guilty pleas.
Maltese was remanded in custody ahead of sentencing at a later date.
