Mobile phone use is continuing to reduce the amount of time people spend using landlines, according to a report by the UK communications watchdog. For the first time, calls from mobiles now account for more than a third of time spent on phone calls, Ofcom said.

Mobile phone call minutes totalled 82 billion last year, in an overall total of 234 billion. And 9% of UK households rely solely on mobile phones, compared with 7% that only have a landline, the report added.
