Question: Can a person with dementia vote in the UK general and local elections.

Answer: Yes, a person with dementia can vote regardless of their capacity.
It is clearly stated in the Electoral Commission's guidance for Electoral Registration Officers that mental health conditions do not constitute a legal incapacity to vote, so a person would not be stopped from voting at the polling station.
However, it is important to note that the guidelines also state that the decision as to whether and how to vote at an election must be made by the elector themselves, and not by a carer or a person making decisions on behalf of the elector.
