People won't be able to leave the UK from next week under a new law being brought in.
The ban on leaving the UK, unless you have a "reasonable excuse" is included in a set of new coronavirus laws coming into force next week.
The legislation for restrictions over the coming months, as the Government sets out its roadmap for coming out of lockdown, was published on Monday.
Entitled the Health Protection (Coronavirus, Restrictions) (Steps) (England) Regulations 2021, the laws come into force on March 29.
According to the legal document: "The Regulations also impose restrictions on leaving the United Kingdom without a reasonable excuse (regulation 8)."
The law says no-one may "leave England to travel to a destination outside the United Kingdom, or travel to, or be present at, an embarkation point for the purpose of travelling from there to a destination outside the United Kingdom" without a reasonable excuse.
It suggests anyone who breaks such rules could face a £5,000 fine.

The rules must be reviewed by the Government every 35 days, according to the legal papers.
Under the lockdown easing roadmap people are unable to go on holiday abroad until May 17 when international travel could be allowed again.
But today Minister Helen Whately warned people against booking holidays abroad this summer.
Ms Whately spoke to BBC Breakfast about the issue and said: "What I would council is caution at the moment for people to hold off on booking, because as anybody can see, we're in a situation were there are rising rates in many countries in Europe.
"We know that also something that comes with rising rates is increased risk of variants, [that's] why it's so important that we're going to be able to test more rapidly for variants of concern.
"So I would say to people, just hold off. What matters for us at the moment is that we keep pressing on with our vaccination programme and we've got this tremendous situation where half of UK adults have been vaccinated."
She added: "Look, let's keep pressing ahead with that and the steps that we're taking to control the virus here in the UK."
