In a 'no-chairing stunt', opposition party leaders left an empty chair for the Prime Minister at the meeting. Theresa May was in a cabinet meeting atthe time.

Organisers of Miss Thunberg's event said that no response had been received to their invitation to the Prime Minister, but they were still hopeful she might attend at least part of the discussion.

Jeremy Corbyn tweeted: 'It was a pleasure welcoming UK youth climate strikers and Greta Thunberg to parliament.
