Acevo chief executive Sir Stephen Bubb was forced to eat his words from a recent blog about right-wing politicians that "hate" campaigning charities after Conservative MP Robert Halfon described it as offensive and outrageous.

Sir Stephen wrote the blog shortly after The Daily Telegraph published an article in the summer which criticised various international aid charities for paying their chief executives more than £100,000 while their income was declining.

He wrote that many MPs on the Right "hated charities who campaign and particularly dislike international charities that have been so effective at raising the concerns of the world's poor".

Halfon seized his opportunity to publicly harangue Sir Stephen over the blog at a meeting of the Public Administration Select Committee this morning, where the Acevo chief was giving evidence on the subject of charity executive pay.

He said he considered himself  to be "on the Right" and listed a number of international causes that he has personally been involved with, before stating that he found Sir Stephen's remarks "quite offensive" and "stereotypical".

He then went on: "It's the equivalent of me saying that you, Sir Stephen, are a quangocrat aristocrat that lives off the taxpayer and leeches off the charitable sector and has his birthday parties at the expense of the taxpayer and the charity sector - but I wouldn't say that because I don't believe in stereotyping.

"Wouldn't you agree that your comments were wrong and outrageous?"

In response, Sir Stephen said that Halfon had already raised this with him privately and that he agreed his comments were ill-advised. "That was stereotyping and a generalisation which I regret," he said.
