Boris Johnson will on Friday pledge to donate most of the UK’s surplus coronavirus vaccines to poorer nations.
At a virtual meeting of G7 leaders, the prime minister will confirm that the majority of the UK’s spare doses will be given to the international Covax initiative, which aims to give equitable access to Covid-19 vaccines.
However, the UK will not detail the timing and scale of the donation until later this year.
This comes as a report by anti-poverty campaigners suggests that rich countries are set to have 1 billion more doses than they need to vaccinate their own populations.
Elsewhere, Mr Johnson has been warned by leading health organisations that frontline NHS staff are at risk from the airborne transmission of coronavirus.
A group of more than 20 health and science bodies have written to him asking for health workers to be given higher grade masks.
