If so, top tip if you have a sitting MP candidate -
Bring your phone with you and look up their voting record in parliament then when they start talking about being all in favour of something that completely contradicts their voting record you can pull them up on it live.
Doesn't matter which party they re from, if (for example) they start saying we all need to act on the environment and their voting record shows they have voted AGAINST measures to take action on climate change at every opportunity, you can point out to the room how they actually vote.
