25 January 2013 Last updated at 22:47 GMT

Samsung Electronics said its profits surged 76% in the last three months of 2012, helped by sales of its Galaxy smartphones.

Net income rose to a record 7.04tn won ($6.6bn; £4.2bn), up from 4.01tn won in the same period a year earlier, beating analysts' expectations.

The Korean firm said its mobile profits more than doubled over the same period.
