This is a red herring. During the election, the Conservative Party campaigned on the basis of a manifesto that included the pledge to hold an in/out EU referendum. It is hardly reasonable, now that the Conservatives are in government, that they should not be able to take a stance on the issue. Should they just leave it to others to put the case for and/or against remaining in the EU? No, the Conservatives won the election and they now have the mandate and majority to pursue and campaign on the issue of the UK’s relationship with the EU.
