E.ON profits 'to raise questions'

One of the UK's big six energy suppliers will leave customers "questioning" their bills after it more than trebled its net profits, a consumer group has warned.

E.ON, which has more than five million customers in the UK, reported underlying net income for the January to June period of 3.3 billion euro (£2.6 billion) compared with around 900 million euro (£706 million) a year earlier.
