During Wednesday’s coronavirus press briefing (10 June), Johnson was asked what the government was doing "to ensure the safety of the cruise sector" and protect thousands of jobs.

Johnson conceded cruise would have to go through "a period of self-reinvention" to become Covid-secure, but backed the sector’s resilience to emerge from the coronavirus crisis.

"I have no doubt it [cruise] can do it," said Johnson. "It is a great, great British industry, and we will support it in any way we can."

Andy Harmer, Clia director UK and Ireland, said: “The prime minister’s words of support for the cruise industry are very welcome. The cruise industry voluntarily suspended operations as it was the right thing to do while the world addressed the global health crisis.

"However, the impact of this suspension is being felt heavily not only by cruise lines, but by people whose livelihoods depend upon the cruise industry, such as travel agents, tour operators, taxi drivers, and hoteliers."

Harmer confirmed the sector was already working with officials to ensure a safe restart. “As the prime minister has said, the cruise industry is a ‘great British industry’," said Harmer. "The industry generates £10 billion to the UK economy each year. It is also a resilient industry.

"We are currently working closely with the government, health authorities and ports to develop even more enhanced health protocols as we plan for the future resumption of operations. We look forward to playing our part in the country’s economic recovery.”
