HUNDREDS of Kirklees people will not be able to vote in important elections this year.
Teenagers coming of age and people who have moved house are the two groups most likely to fall off the electoral register.
The warning comes in the year the Government has moved the date of council and Greater London Authority elections to June 10, so they take place at the same time as voting for the European Parliament.
It is estimated that 858 people in Huddersfield will be unable to vote, along with 331 in Dewsbury and 233 in Batley and Spen. In Calderdale, 883 citizens will miss out on their democratic right.
Throughout Yorkshire, about 50,000 people are not yet registered to vote.
The figure for the whole of the UK is 11.4m.
Anne Hinds, the Electoral Commission's communications director, said: "We know people feel passionately about the issues that are important to them.
"But if they are not registered to vote they won't be able to influence how things are run.
"Many people assume that their details are automatically updated when they move - but this isn't the case."
Electoral registration forms can be found at www.electoralcommission.org.uk or by contacting councils by the registration deadline of Tuesday, April 13.
