The Guardian leads on the NHS strikes taking place this week, which are believed to be the biggest in the health service’s 75-year history. Ten chief nurses have warned that the deadlock over pay is “putting patients in danger” and “risks hardening unions’ positions”. It also reports that one in ten police officers have slipped through recruitment vetting, with “hundreds” of officers, including some with previous convictions and close links to criminals, being mistakenly hired since 2020.
