The FCO has changed its stance on the country and no longer advises against all but essential travel. Instead, the warning is merely to view the FCO advice before travelling.

The UK government advised against all but essential travel following Easter’s terrorist attacks in which more than 250 people were killed in bombings that targeted hotels and churches.

This led to operators including Tui pulling its clients out and removing the destination from sale.

The FCO website now gives a green coding to the entire island despite warning that terrorists “are very likely to carry out attacks” and that curfews are still being imposed in some areas.

Abercrombie & Kent said it was "thrilled" to learn the FCO ban had been lifted.

Managing director Kerry Golds said: “Sri Lanka is brimming with lush landscapes, ancient treasures and amazing people. Now is the time that they need our support. Tourism is a big part of their economy and the FCO update is only good news for the Sri Lankan people.

"Our local office on the ground there means that A&K are with you every step of the way for those who may still be cautious about travelling.”

Malik Fernando, owner of Resplendent Ceylon hotels, added: “Tourism is a large part of our economy supporting one in 10 families in Sri Lanka, so the FCO update is excellent news.

"We have a close connection with the UK as one our biggest inbound markets and look forward to welcoming visitors back with open arms.

"We are extremely grateful for the outpouring of support over the past month and have no doubt that a bright and peaceful future lies ahead.”
