A Liberal Democrat MP joked about Labour's performance at the Eastleigh by-election and teased David Cameron over his previous "fruitcakes and closet racists" comments about UKIP.
But David Cameron initially seemed more interested in Sir Bob Russell's yellow waistcoat - and he also sported matching socks and tie - for his question in the House of Commons.
At PMQs, both coalition partners revelled in Labour's fourth place in last week's poll in the Hampshire seat, where UKIP beat the Tories into third place.
