The unions are funding Labour with public money voted to them while Labour were I n power “the union modernisation fund” a little li the cash stockpiled by trot councils against a “rainy” day!!!Some years ago the Labour party were very very broke. However, they never had to face the music. I doubt they ever will. The Unions will keep bailing them out.
In my experience our left leaning colleagues are always keen to use someone else’s money rather than their own.
