Government ministers have asked London Mayor Sadiq Khan to clarify what legal barriers he believes were preventing him from sending Ultra Low Emission Zone (ULEZ) non-compliant vehicles to Ukraine.
It comes after the mayor, who previously refused to send the vehicles, asked Transport Secretary Mark Harper and Levelling Up, Housing and Communities Secretary Michael Gove to enable Londoners, and others across the country, to donate suitable vehicles to Ukraine through scrappage schemes.
