The deal could be one of the biggest in the telecoms world
Vodafone has confirmed it is in talks with US company Verizon Communications over the sale of its 45% stake in their joint venture, Verizon Wireless.
Reports earlier this year suggested that Verizon was looking to buy Vodafone's stake in Verizon Wireless for about $100bn (£64.5bn).
However, there has also been speculation that the stake is worth more than this.
Shares in Vodafone jumped 8% following the company's announcement.
Vodafone said in a statement: "Vodafone notes the recent press speculation and confirms that it is in discussions with Verizon Communications Inc. regarding the possible disposal of Vodafone's US group whose principal asset is its 45% interest in Verizon Wireless.
"There is no certainty that an agreement will be reached."
