Has there ever been a situation where a modern Westminster parliament (national/federal/state/provincial) has ended up with more independent lower house MPs than MPs belonging to the second-largest party/coalition? In particular has there ever been a case of an independent MP being designated as Leader of the Opposition?
It appears that Australia's Northern Territory Legislative Assembly, following the 2016 election, will end up with the Country Liberals (one of the two traditional major parties) having only 3 seats, compared to 4 independents. I'm curious as to whether there is much modern precedent here.
