So long as the Tories do not have an overall majority, there will be a majority in the House of Commons for giving people a chance to vote on changing the electoral system so that it will be impossible for any MP to be elected unless at least 50 per cent of the voters agreed to that happening.

Even if the Tories, who are against that, do manage to set up a minority government, they cannot stop that referendum happening.

That would mean that there will never again be a government elected on a derisory minority vote.
