Unions warn strikes could last six months as Rishi Sunak grilled: ‘Where have you been?’

The prime minister has rejected calls for talks with striking workers

Rishi Sunak has been challenged about accusations he has been missing in action over strikes as unions warned unprecedented travel chaos across the country could continue for at least another six months.

The prime minister was also told there would be a “huge escalation” in industrial action next month unless ministers enter into pay talks.

The warnings came as the prime minister was asked to explain “where have you been” after a week of walkouts across the country, including by ambulance staff and nurses.
