The Police and Crime Commissioner (PCC) does not run the police but is responsible for holding the police to account for the public. The current PCC is Clive Grunshaw who was elected in 2012.
The voting system for PCC elections is different to other elections in that voters choose a first and second preference candidate. If no candidate receives more than 50% of the vote, the top two candidates are then put through to the second round, where the second preference votes of all other candidates are counted to find a top two. The candidate with the most second preference votes across Lancashire is then elected.
The full list of candidates will be confirmed on April 13.
