Tesco Mobile chief executive Lance Batchelor is leaving the supermarket.

Batchelor, who has headed up Tesco’s mobile and telecoms business since 2007, leaves at the end of February according to The Independent.

He will be replaced by current commercial director for non-food hardlines Graham Harris.

The grocer said its mobile customer base grew to more than 2.5 million on Christmas Day as tens of thousands of Tesco Mobile handsets were activated on Christmas Day.

Tesco Mobile is a joint venture between the grocer and O2.
