Tory MP David Davies had a furious row with a radio phone-in caller over the teaching of Welsh in school.
The Monmouth MP came up against Radio 2 listener Maureen Boyardy from Treorchy, Rhondda Cynon Taf, who supports the compulsory teaching of Welsh language in schools.
As the argument became more heated, Mr Davies appeared to lose his temper and said: "Why don't you join the BNP where you belong".
The Jeremy Vine show is broadcast Monday to Friday at 12:00 BST on BBC Radio 2. Listen again via the link (UK listeners only).
