The ban extends to the Nottingham Post and BBC-funded local democracy journalists managed by the paper, with councillors instructed not to speak to them and press officers to remove them from media lists.
Nottingham Post editor Natalie Fahy stated the move is a "worrying sign of potentially things to come if Reform wins the next election," highlighting concerns about the shutting down of questioning.
The Liberal Democrats criticised the decision as being "straight out of Donald Trump's playbook" and urged Nigel Farage to intervene, while Labour accused Reform of "rank hypocrisy."
The ban reportedly followed a viral interview clip of a local councillor and a story published by the Nottingham Post concerning internal disagreements within Reform's council group.
