PM BORIS Johnson’s vaccine passports risk creating “Checkpoint Britain”, Tory MPs warned yesterday.
The 70-strong Covid Research Group (CRG) said a plan to use them in shops was “incompatible with freedom”.

And Labour also said they objected to Covid-Status Certification — the passports — in their current form.
Mr Johnson is considering introducing digital passports in England in June.
They would show if someone has had the jab, a negative test or natural immunity.
Under the proposals, they would not be needed on public transport, public services and “essential shops”.
The PM’s spokesman confirmed they may be needed to enter “non-essential” shops like Next or Primark.
CRG deputy Steve Baker said the proposal would “lead to a two-tier Britain”.
He said it would waste taxpayer cash and discriminate against ethnic minorities and pregnant women who are less likely to get a jab.
David Davis said the scheme carried database and collation risk that could “impinge on privacy”.
A Labour source said the party would vote against Covid passports in Parliament as they stand.
