Boris Johnson hailed a new "milestone" in the race to vaccinate the country, as more than five and a half million additional people will be invited to get their jabs from today.

Ten new mass vaccination sites opened this morning. NHS England chief Sir Simon Stevens said the health service would start 24-hour hospital vaccinations within 10 days - something resisted by management consultants paid to speed up the programme.
