Have a look at 'Jubilee' plum on Pixy rootstock. It is a modern variety and an improvement on Victoria. Otherwise, have a look around at which variety is most suitable for your part of the country.

West Yorkshire, thanks for the answer

Quickly searching for Jubilee I note a new dwarfing rootstock has replaced Pixy, may as well get the latest breeding if buying one
