Samsung's Apple defeat hits shares

27 August 2012 Last updated at 15:33 BST

Shares in Samsung fell 7% in Seoul during Monday trading, their biggest one-day fall in almost four years, after the electronics giant lost its court battle with Apple.

On Friday a US court ordered the South Korean company to pay $1bn in compensation to its rival over claims of copied designs, and Monday's trade saw almost $12bn disappear from its value.
