Not really - the headline notes that the election was boycotted by the other major parties, so while his vote share increased 17.1% the 2nd through 5th placed parties last time didn't run and they previously won 52.7% of the vote.

Both Tory and Labour boycotted this publicity stunt election, that’s why he had increased support.
