Shares in Huntingdon Life Sciences Group halved last week following a series of threats by animal rights protestors who accuse the laboratory of 'hideous animal suffering and misery'.
Camden's shares in the company are held as part of the council's pension fund. Other key shareholders include the Labour Party and West Sussex CC, promised to sell their shares immediately following intense lobbying.
But John Dickie, chairman of Camden's investment panel, said they had received a letter from the fund managers to say the shares were only under review. He did not know if the shares had been sold. He added that the council's ethical share-holding policy only stretched to tobacco companies, but was being reviewed this week.
'Camden Council has always aimed to avoid investing in companies which may be ethically inappropriate, we refused to invest in South African companies prior to the abolition of the apartheid regime.'
