According to The Guardian, the Abu Dhabi Investment Authority (ADIA) is understood to have written to the board of Coroin, the company behind the hotels, declaring its interest in acquiring the three luxury properties.
The hotels are currently controlled by the Barclay brothers, owners of the Telegraph newspapers, who have a majority stake in the group.
The Guardian reported long-standing minority shareholder Paddy McKillen has also recently indicated he wants to buy out others shareholders and own the business in its entirety.
The hotels are popular choices for events and conferences. Claridge's offers eight different spaces including a grand ballroom, which can hold 450 for a reception; the Connaught has nine function rooms, the largest accommodating 200 delegates; and the Berkeley has six capable of hosting between 10 and 450 guests.
