Carphone Warehouse chief executive Charles Dunstone said: 'This has been a busy six months, during which Carphone Warehouse has delivered another very strong set of results and invested significantly in building its platform for future growth.'
In early October, mobile phone giant Vodafone ditched Carphone Warehouse in favour of rival firm Phones 4U as the exclusive retailer of its mobile phone contracts.
But Dunstone said: 'Subsequent to its announcement on October 12, we have been actively engaged with Vodafone regarding the development of a pan-European framework agreement.'
