Has any party ever lost as badly as the Progressive Conservatives in 1993?

[Stranger in a strange land]

In 1993, the Canadian Progressive Conservatives lost 149 out of 151 seats in the House of Commons, ending up with two. Percentage-wise, this was more than a 98% loss, which took them from largest parliamentary bloc to virtual non-entity. Has anything comparable ever happened in another democracy?

I seem to recall a government party being wiped out entirely in an fptp election in... was that Mauritius? Anyways, a much smaller parliament of course.

It happened in New Brunswick in 1987. The Conservatives went from 39 seats (forming the government) to 0.

I'm not aware of anything on the PC level.
Worst Irish collapse:

Irish Parliamentary Party

Election	Seats	Votes
1910	74	90,416
1918	7	226,498

The votes tally is grossly misleading though as many of the 1910 victories were uncontested.

UK Conservatives went from 343 notional seats to 165 actual seats in 1997

I know of a couple that is not as bad might somewhat close.

1993 France. Left Alliance went from 303 out of 575 in 1988 to 91 out of 577 in 1993.
1977 India.  INC(I) went from 352 out of 545 to 154 out of 545

2 near examples of bad results,in both cases the government had resigned not long before election to be replaced by caretaker/colaition ones(UK examples):
1906:Conservatives reduced from 402 to 157 seats and 1929:Labour reduced from 288 to 52 seats!

Canada does this a lot. The NDP in British Columbia dropped from 39 seats and forming the government to just two seats in the 2001 election. The PEI Conservatives dropped from 18 seats and government to zero seats in 1935.

The worst collapses in Dutch history I can think of are PvdA in 2002 (from 45 to 23),
CDA in 1994 (from 54 to 34) and Pim Fortuyn List in 2003 (from 26 to 8 ).

The Iran Participation Front went from over 100 seats in the 2000-2004 Majlis to zero in the 2004-2008 one. But that was largely the fault of the Council of Guardians not the voters. They would have done badly regardless though

the second example should be 1931 not 1929.sorry!
