You mean, if the result is a blatant "travesty" of the popular vote. I think you may have a point. I do remember there was an election (2015?) where the SNP got about 50 seats and UKIP got about one but with a higher share of the vote.
And this election could plausible produce this kind of non-sense on stilts.
So the latest polling from Redfield & Wilton, published 30 mins ago has the following headline voting intention:
Labour 43% (+1)
Reform UK 18% (+1)
Conservative 18% (–)
Lib Dem 12% (-1)
Green 5% (–)
SNP 3% (–)
Other 1% (–)
Put into a seat predictor (and without tactical voting) you get:
Lab 512
LD 57
Con 31
SNP 21
Ref 4
PC 4
Green 2
Others 19
So the party that:
Gets 43% of the vote ends up with 80% of the seats
The party that is equal second in popular vote gets 4 seats (equal 5th in parliamentary seat terms)
The official opposition is the party that comes 4th in the popular vote
And a party that gets just 3% of the vote ends up with 21 seats
