Health Secretary Matt Hancock said the July 19 easing of lockdown restrictions is on track, but warned that opening up international travel for the summer holidays is "more difficult".

The lockdown restrictions are due to be removed on July 19, with schools due to close for the summer on July 23.

The six week summer break signals the start of the peak holiday season, but holidaymakers hoping to jet off face uncertainty over whether their trips will go ahead.

Currently, no major summer holiday destinations are on the UK's quarantine-free green travel list, although that is set to be updated by June 28.

Mr Hancock said ministers are working on plans to allow fully vaccinated Britons to travel abroad without having to quarantine when they return, although many younger adults will only have had one vaccine shot by August.

“This hasn’t been clinically advised yet – we’re working on it,” the Health Secretary told Sky News.

“We’re working on plans to essentially allow the vaccine to bring back some of the freedoms that have had to be restricted to keep people safe.

“After all, that’s the whole purpose of the vaccination programme, that’s why it’s so important that every adult goes out and gets the jab.”

Asked if these plans could be in place as soon as August, the Health Secretary replied: “We’ll get there when it’s safe to do so.”

Mr Hancock acknowledged that reopening international travel is more difficult than ending restrictions at home.

“Thankfully, because of the vaccination programme, we have been able to free up a huge number of the restrictions here at home,” he told Sky News.

“We are on track to deliver the Step 4, the further openings, on July 19, which is good.

“We are also looking to see how we can replace the protections that are currently there with the restrictions with protections that come from the vaccine, with respect to international travel as well.

“But it is more difficult freeing up international travel.”

Mr Hancock has said the main NHS App, which is different from the Covid-19 App, is “important” as countries are likely to need proof of vaccination status of Britons travelling abroad.

“We can now, all of us, see our vaccine status, see your testing status, on the NHS App,” he told Sky News.

“Six million people have now downloaded the main NHS App and on that you can show whether you have had the jabs.

“It’s important because we know other countries are going to say that they want proof that you have been vaccinated before you go.

“So, when travel is opened up, we are going to make sure people have got that ability to prove it.”
