MPs are due to vote on the proposed laws on Thursday, March 25.
If approved, which seems likely, the rules will come into effect on March 29.
They will remain in force until June 30, with Health Secretary Matt Hancock suggesting holidays may be permitted after that date.
This is in direct contradiction to the suggested dates on the coronavirus lockdown easing roadmap.
According to Boris Johnson’s lockdown easing plan, breaks in the UK may be permitted from April 12.
Holidays overseas may be permitted from May 17.
This date prompted many holiday-starved Britons to book vacations abroad after this date.
But now they are facing potential fines if they continue with their holiday plans.
