Prince Walter is the consort of the heir apparent to the British throne, a position he has no intention of relinquishing to a commoner, and an American to boot. He therefore connives with Templeton to ensure that his bride is never able to file for divorce, and is thwarted, and unmasked, by the efforts of Chance and his team in "Victoria". He appears to lack adequate backbone to stand up to Templeton, although he does attempt the bluff - momentarily.
Walter is portrayed by Robert Lawrenson.
