Bristol has 93% of eligible voters on electoral roll
The number of people registered on Bristol's electoral roll is the highest recorded figure the city has had, according to the council.
Following an annual canvass, the city council said that 93% of eligible voters were now registered.
It said the city was "bucking a national trend". A recent Electoral Commission report showed a 50% rise in unregistered voters in the past decade.
The council said those still to register could do so via its website.
Liberal Democrat councillor Trevor Blythe said: "The referendum for an elected mayor is due to take place on Thursday, May 3rd.
"This will be a city-wide election. If there is a 'yes' result then elections for a Bristol mayor will be held on the same day as the police commissioner elections for Avon and Somerset on Thursday November 15th 2012."
