At Prime Minister’s Questions, Labour leader Kier Starmer said: “around three in ten people who should be self-isolating aren’t doing so.”

On Monday, he repeated this claim but said the opposite – that only three in ten people were self-isolating fully.

This latter claim is supported by data released by the Scientific Advisory Group for Emergencies (Sage), which advises the government on the pandemic.

It said that just 29% of people who had symptoms of coronavirus were full adhering to self-isolation rules. It described this as “sub optimal”.

It’s difficult to get a precise figure on the amount of people who do self-isolate because they are generally based on surveys.

However, most of these surveys suggest the majority of people do not adhere to the full ten-day isolation period.

The government has said that £500 payments are available to support those who might face financial difficulties whilst self-isolating.

Again, there is no publicly-available data on this, but freedom of information requests to local councils have shown that the majority of people who apply are rejected due to the tough eligibility criteria.

Speaking about the UK vaccination programme at Prime Minister’s Questions, Boris Johnson made this claim about the Labour leader, Keir Starmer: “One week he calls for us to go faster with rolling out vaccines when he would have stayed in the European Medicines Agency [EMA], which would have made that rollout impossible”.

We’ve covered this argument before and it’s a claim the Prime Minister has made repeatedly.

It’s clear that the UK has done a better job than countries in the EU in approving and distributing vaccines quickly. But the head of the UK’s own medicines regulator, the MHRA, has said the UK’s early approval was permitted under EU law.

If the UK had stayed part of the EMA (the EU’s medicines regulator), there would have been political pressure to go with the majority on both the approval and distribution of vaccines. But that was equally true in the past about other big issues, such as joining the euro, or the passport-free Schengen area. And the UK joined neither.

Staying in the EMA might have made it harder for the UK to act alone, but it wouldn’t have made it impossible.
