Cllr Phil Taylor, who represents a ward in Ealing in west London later blogged that it was "an off the cuff, ironic comment" and "if David Attenborough is unhappy I am sorry."

Sir David Attenborough is "wrong" for his comments on aid where he said it was "barmy" attempting to solve famine in Africa by sending bags of flour, Oxfam said.

“David Attenborough is wrong – there is plenty of food in the world to feed everyone if we share what we have more fairly. Also, we could easily boost production by reversing decades of under-investment in poor countries' agriculture.
"Of course we need to act to reduce climate change and protect scarce natural resources but that does not mean turning our backs on people in dire situations who need our help."
