"The UK has stockpiled millions of doses of tamiflu. A flu pandemic is the gravest threat to UK security as it could claim up to 750,000 lives, according to a new National Risk Register. The document, published for the first time, weighs up the likelihood of threats and their potential impact. The most likely threats are attacks on the transport network and on computer and communications systems. The information had been kept secret up until now. The register will be updated annually by the Cabinet Office."
