Mark this up as a moment in history - as Parliament held court today to one of the largest protests it has ever seen - more than 35,000 people descending on the capital - to close out a nine day hikoi. They rallied in opposition to the government's agenda for Maori, but chiefly the Treaty Principles Bill, championed by ACT's leader David Seymour. The man himself briefly faced the crowd - but was boo'd back into the Beehive - as protesters chanted: 'kill the bill'. Deputy political editor Craig McCulloch spoke to Lisa Owen.
