The shortlist has been announced for the WhatsOnStage Awards for 2018. Aidan Turner and the play The Lieutenant of Inishmore have recieved 6 nominations in total.
You can vote for them in the link below. It says that they allow “one vote per person” and they ask for an email address, so I’m not sure if it’s actually “One vote per email address”. You do not have to vote for every category.
