MPs back investigation into claims Boris Johnson misled parliament

First, Tory MPs were told they should vote against a Labour attempt to kickstart a Commons investigation into whether Boris Johnson misled MPs about lockdown parties.

Then, at the 11th hour this morning, a screeching U-turn – MPs would be allowed a free vote.

It turned what was expected to be a day of fiery partisan argument into something quieter, but perhaps more devastating for the prime minister.
