Could it be that Labour leader Ed Miliband's demand that all school pupils must study maths until they are 18 has been prompted by new evidence that his own MPs struggle with numbers?
The man in charge of the party's policy review, Jon Cruddas, admitted this weekend that he is "barely numerate". And when the Royal Statistical Society (RSS) recently tested the ability of honourable members to answer a relatively simple mathematical question, only a quarter of Labour MPs got it right.
A total of 97 MPs were asked this probability problem: if you spin a coin twice, what is the probability of getting two heads?*
Among Conservative members, 47% gave the wrong answer, which is disappointing enough. But of the 44 Labour MPs who took part, 77% answered incorrectly.
