Council staff in part of Fleetwood, Lancashire were taking stringent precautions to avoid confusion for voters. The three contests were:
A poll to fill the last three remaining seats in Wyre BC's Warren ward, delayed from 6 May by a candidate's death
A by election for Lancashire CC's Marine division
Adding to the complexity is that the voting procedure for each is slightly different.
For the European contest, voters had to make their mark against a party, not a candidate. In the county poll, they put their cross against one candidate. But in the borough election, they had to vote for each of the three seats.
Wyre BC chief executive Michael Brown said: 'Every effort will be made to eliminate any confusion and make the voting process as easy as possible.'
Voting at polling stations took place in two rooms - one for Europe and one for the councils.
