William Hague on top threats to UK security
William Hague says that cyber attacks, alongside international terrorism, military conflict and natural hazards such as a flu pandemic, are among the key dangers to UK security.
The threats are outlined in the government's new national security strategy.
There will be an extra £500m to bolster cyber security, focused on protecting key infrastructure and defence assets.
The foreign secretary said it was crucial that the country was able to protect itself against cyber attacks.
