Jacob Rees-Mogg has demanded that cabinet ministers do more to get their civil servants back to the office after the vast majority of Whitehall departments were found still to be operating at less than half of their normal capacity.

An audit conducted across Whitehall shows that calls by ministers for civil servants to return to the office have gone largely unheeded almost three months after work-from-home guidance was lifted. - The Times

British households have cancelled their streaming subscriptions in record numbers so far this year as families continue to grapple with the rising cost of living.

In a statement at around 1530 BST on Tuesday, Mr Johnson will "have his say" on the scandal that has destabilised his premiership and "outline his version of events" before taking questions - The Independent
