In the most important election in living memory, the Observer will make sure the candidates get asked the right questions. We will be putting them on the spot as part of the campaign and we want to know what you want to know. If you would like to quiz the hopefuls, email your question to ben.higgins@trbeckett.co.uk. Please include your full name, age, street address and occupation. We will select the best/most common questions and put them to all the candidates, so please make sure they are not specific questions for one candidate.
