But furious Kim has warned the UK not to go forward with the operation, condemning it as a hostile act. A spokesman for state-owned Korean Central News (KCNA) agency warned: “This is a never-to-be pardoned serious challenge to peace and security.” The spokesman also said Britain should “immediately withdraw its decision to take part in the military drills for aggression”. KCNA went on to warn that the military equipment involved in the drills will be within the site of the Pyongyang’s military.

The communist state's inflammatory comments come just weeks after South Korea’s Air Force announced it will stage the Invincible Shield drill with Britain and the US from November 4-10. The drill is a bid to improve Seoul’s capabilities to attack North Korea’s major leadership facilities and intercept incoming aerial assaults. The warning comes amid heightened tensions between Pyongyang and South Korea following Kim’s nuclear test in January which has been followed by a series of ballistic missile launches.
