Who's going to write "None of the above" on their ballot paper tomorrow?

That would be recorded as a spoiled ballot paper.

Earlier this year there was a petition (now closed because the 2019 - 2024 parliament has ended) on the UK Government petitions website:

https://petition.parliament.uk/petitions/650023

which said:

"Implement "None of the above" on ballots in all United Kingdom elections #NOTAUK

I urge the UK Government to permanently adopt "None of the above" on all ballots starting with the next general election, to enhance democratic choice and allow voters to express dissatisfaction. If NOTA wins most votes, consider rerunning the election, possibly with initial candidates disqualified. ... ".

Maybe when the new parliament starts, perhaps someone could start a similar petition.

There is a Wikipedia page on this topic:

and there have been instances where a "none of the above" vote has lead to a rerun of the poll.
