From latest Private Eye, and posted hoping that people buy it rather than not having to;
'For all the ministerial hand wringing, why is the government so impotent in the face of the Cadbury takeover?
Largely because one of business secretary Lord Mandelson's predeccessors, Patricia Hewitt, put through legislation laughably called the enterprise act in 2002. This removed any public interest test from the process of approving mergers beyond whether competition would be affected (except where national security or the media are involved) and prevented the trade secretary from intervening as he or she previously could.
The efect is that, for all his pledges to restore British industry, Mandelson is reduced to pleading with the American processed cheese maker to leave a few chocolatey crumbs in the country.'
