The decision to add the destinations has been made as the operator continues its expansion into the long-haul market.

A total of two hotels will be on offer in Sri Lanka, The Vivanta by Taj Bentota which, thanks to its location on the south west coast offers whale watching expeditions as well as river cruising trips, while The Fortress in Galle is a 53-room boutique property.

Meanwhile, the two new Far Eastern cities have been added with the opportunity of bolting them on to other trips, for instance a Thai beach break or as a stopover on the way to Bali.

Newly featured properties in both cities focus on the luxurious, with both the Harbour Grand Kowloon, the Park Lane Hong Kong and A Pullman Hotel available in Hong Kong while the Shangri-La Singapore and Raffles Hotel Singapore are also available to book.

­Sovereign is offering a 10-night Singapore and Bali trip leading in at £1,859pp, including three nights in Singapore’s Raffles and a further seven nights at The Laguna – A Luxury Collection Resort, both on a B&B basis and including flights and transfers, departing April 30.
