In fact, make him give a third of it to Momentum. If another third therefore went to Progress, then so be it.
By his own choice, he was banned from any political activity whatever throughout his adult life, until weeks before he entered Parliament.
Whereas they have been full-time political activists since he was still in school, or in some cases since before he was born.
Thanks to the boundary changes, at least one of him and Dugher will have to leave Parliament in 2020, anyway.
