When the 1992 general election produced such a surprise win for the Conservatives political pollsters & others devoted a huge amount of time & effort analysing what had happened
As someone who has lived in other countries it surprised me (in a nice way) that nobody ever raised the possibility of fixed or fraudulent voting. Except for one short item about worries over the handling of proxy or postal votes from residents of one small old peoples home somewhere in the south west
Even with the restricted possibilities for voting other than in person which existed then, it was not hard to think of ways that the election could have been rigged
I am not for a moment suggesting that it was fixed, just commenting on the fact that everybody took it completely for granted that such things do not happen here
Hence, I suppose, the naivety with which the rush to postal voting on demand took place
