The boss of London's Heathrow Airport has asked Britain to rebuild confidence in travel by making it easier to go abroad, as speculation grow that the government is poised to slap yet more new rules on arrivals, reports Reuters.

Britain has reopened its borders to large parts of the world, scrapping quarantine for fully vaccinated arrivals from the European Union and the US, in a boost for airlines and travel companies brought to their knees by the pandemic.

But just as families and business travellers arrived at airports like London's Heathrow, the industry faced a new headache over potential Covid-19 warnings against holidays to Spain.

Heathrow's chief executive has called on the government not to throw new barriers in the way of travel just as it finds its feet again.

“Let's just make it easier now for people to travel,” he told Reuters in the arrivals hall. “I think we just need to keep things simple. We need to build confidence in travel.”
