Not Quite! They can fly in accordance with IFR and with less than VMC cloud clearance (which by definition means they are not in VMC and hence in IMC) so long as they are In Sight Of Surface and have the required in flight visibility. (This ability to fly IFR in Class G, in some IMC is an odd feature of the CAA PPL)
