Around 200 tourist boards, destinations and other exhibitors have confirmed attendance for the November event.

In an online update, the event’s head of sales, Jonathan Hull, said: “What’s happening on the show floor is essentially mirroring what’s happening in the real world.” He said some regions had been “heavily impacted”.

“There’s huge demand from Europe, but the Americas are heaviest impacted.” He added the Caribbean region was “very, very keen to attend”.

He said he expected participation in some form from all countries that normally attend.

Organisers say they are confident the show will go ahead, although the two day event at ExCeL will be followed a week later by a virtual event.

WTM London event director Simon Press said the addition of the virtual event “should cover off all unforeseen circumstances”. He said a trial of this at Arabian Travel Market in June had been successful.

Precautions at ExCeL will include increased ventilation, one-way systems, capacity management and increased spacing. All food will be pre-packaged and increased transport options are being examined.
