Cardinal Becciu, who has not been placed under investigation, has denied any wrongdoing.
The Vatican is considering the sale of a luxury London building embroiled in a financial scandal that drew papal condemnation and a probe into those involved in its purchase seven years ago.
Now authorities of the walled city-state within Rome have invited brokers to pitch for options that include the potential sale of 60 Sloane Avenue in Chelsea, people with knowledge of the process said.
The building is valued at about 200 million pounds ($277 million), the people said, asking not to be identified because the process is private. The property is located in one of the most sought-after and rich zip codes in the capital. The Vatican confirmed that a sale is one of the options on the table, while adding that there was no rush to reach a decision.
Originally developed as a car showroom for the Harrods department store, the building spans more than 170,000 square feet (16,000 square meters) of offices and retail space with a neo-classical terracotta facade. It has permission to be converted into 49 luxury apartments.
