The electoral commission has launched an investigation into the Conservative Party over Boris Johnson’s flat refurbishment.
The spending watchdog said there were “reasonable grounds to suspect that an offence or offences may have occurred”.
The PM is under growing pressure to declare how refurbishments were paid for after his former adviser, Dominic Cummings, said there was a plan for donors to “secretly pay”.
Mr Johnson told MPs he had covered the refurbishment “personally”, but would not say who had paid the initial bill.
So why does this matter? And what could it mean for Boris Johnson’s future? Policy Editor Lewis Goodall reports.
