During a Downing Street briefing on Wednesday (8 December), the prime minister was asked: "Why can’t fully vaccinated British travellers, stuck in red-listed countries, self isolate at home when they return, instead of a hotel? Quarantine hotels are too expensive."
In response, Johnson said because the Omicron variant is now "seeded" around the world, the government will "look at the red list and the way we do it".
"It’s been very important in the immediate period, the immediate response to Omicron, to have very tough border measures to slow the arrival of the variant in this country and that was the objective of those measures and continues to be," he added.
It comes after health secretary Sajid Javid hinted the government could very quickly remove its curbs on travel, but played down the prospect of any additional financial or sector-specific support for the industry.
