We’ve been alerted to a misleading claim on social media about the cost of the contact tracing systems in the UK and in Ireland. The post claims the Irish system costs £773,000 and the British system costs £12 billion. But these figures aren’t comparable.

The £773,000 figure is just the cost of Ireland's test and trace app, not the test and trace system as a whole. The chief executive of the Irish Health Service Executive predicts the full-year cost of the system could reach €700 million (around £630 million).

The £12 billion figure refers to the UK government's provision for the whole test and trace system in England, not just an app.

The cost of the app in England and Wales is estimated to be £35 million for development and first-year running costs.

But even using the correct figures, comparing the cost of the systems in the UK and Ireland is tricky, given the vast differences in population, for example.

Claims that Rishi Sunak said musicians and other people in the arts sector “should retrain and find other jobs” have gone viral following an interview with ITV.

Although ITV has since deleted its original tweet, in which it paraphrased the Chancellor’s remarks, many people still insist that is what Mr Sunak meant.

So what did he actually say? We have transcribed the interview in full, so you can look at the evidence and decide for yourself.

• There almost certainly aren’t as many as two million unauthorised immigrants in the UK
• Andy Burnham was wrong about furlough on Question Time
• It's not true that data on causes of death isn't published
