The Speaker intervened when noisy MPs spoke over John Mann, whom John Bercow described as "something of an exotic creature in the House"
The Labour MP asked if it was true that "real wages have fallen by nearly £1,500" since David Cameron took office.
But the prime minister said that Labour complaining about the economy was "like the arsonist complaining to the fire brigade".
