B-C Green Leader Andrew Weaver is pitching proportional representation as part of his party’s democratic reform platform. Weaver is also promising that — if elected — his party would establish a public watchdog to oversee government advertising and would block cabinet ministers from engaging in partisan fundraising. He says the Greens would ban corporate, union and out-of-province donations and place limits on individual contributions. Weaver pointed out that his party banned corporate and union donations in September.
