It is not without precedent that the party that didn't win the most seats or even got the most votes can not take power.

Different time admittedly and less parties but in 1923, the Conservatives got 37% of the vote and Labour got around 30%
The Conservatives won 258 seats, labour won 191.

It was however Labour and Ramsey McDonald,the aprty that came 2nd in seats and votes, who became the govt; albeit only for 10 months as the Liberals then helped block the legislation with the Conservatives.
This could be really different this time however for a much more stable govt:

I have said it before, I will again, the latest projections of seats on the electoral calculus gives the Conservatives likely around 282 seats and Labour around 275,with the SNP on 52.

Neither Labour or the Conservatives in that scenario could govern at all without the support of the SNP.neither of them,it would be impossible.
Unless either Labour allowed the Conservatives to govern or vice versa,
Now can anyone see that coming about.
