Reform UK's Lee Anderson clashed with new Labour MP Fred Thomas who said he did not think the UK should be a place where 'fewer people want to come here'.
Members of the audience in the auditorium at the Reform UK conference chanted "rip it up" as MP for Ashfield Lee Anderson brandished a TV licence letter to the room.
The embattled Prime Minister has been lambasted for what's been seen as cashing in on donations ranging from clothes for his wife to football freebies.
Lee Anderson warned that older generations would be horrified by "nourished grey-haired vegans" bringing London to a standstill "whilst the Met police stood by".
