Appearing as the programme's psephologist, she will be analysing results at the ITV Battleboard - showing maps, constituencies, and key data. Her role focuses on explaining and illustrating the trends of the night - and what they mean for the new Parliament. Prof Green will also draw on British Election Study data to inform her commentary.
This is not the first time Prof Green has taken part in ITV's election coverage: she was part of the team in 2017.
