The number of spoilt ballot papers submitted in the Humberside police and crime commissioner elections was among the lowest in the country.
Analysis of spoilt ballot papers in this month's elections revealed 2,303 ballots were rejected out of 136,071 votes cast – 1.69 per cent.
Across the country, 2.9 per cent of ballots were spoilt – around ten times higher than the figure spoilt in general elections.
The newly-elected commissioner, Conservative Matthew Grove, said: "This was an election for a new position with a different voting format to that of a general or council election, so it was always predicted that there would be a number of spoilt papers for various reasons, including confusion over how to vote for first and second preferences.
"My role, and that of all the other newly elected police and crime commissioners, is to raise the awareness of what we are here to achieve, and if we do an effective job over the next three and a half years, I am sure there will be less spoilt papers when the next election comes around in 2016."
