A day after Sunak pledged to tackle the country's problems, rail workers again took to picket lines as part of a week-long strike that has paralyzed the network, while daily reports document the mounting pressure on hospitals, where patients routinely wait for hours and ambulances queue in car parks.

The worst bout of worker unrest since Margaret Thatcher was in power in the 1980s, combined with the return of double-digit inflation, has produced a sense of malaise in Britain, where living standards are falling at their sharpest rate since records began in the 1950s.

Nurses, paramedics, border force staff and postal workers have also taken strike action, angered by inflation that is at 40-year highs and touched 10.7% in November. Workers in other sectors are balloting for future action.
