Why?

Well professor you seem very keen to criticise the labour party at every available opportunity.

It would seem reasonable that if you feel so strongly about such issues that you should also castigate other political parties if they were guilty of the same "offence"

If, as you suggest, the Conservative Party are not making any efforts in this regard you should vilify them to an even greater extent.

Merely reporting the words of a third party in this instance is meaningless unless you have a point to make.
