I am aware that some mobile phone companies charge significantly over the basic rate. We have had discussions with them, but their pricing policies are very much a matter for them. I want to give my hon. Friend some comfort, however. Since 1 August, the cost of an 0845 number on BT lines has fallen from 3p to 2p a minute. When someone calls our helpline, we are careful to make them aware how long the call will take, and to ensure that they are aware of the mobile phone charges that can accrue to the call. We then advise them that they can phone back on a land-line if they want to do so. If they cannot do that, our advisers will call them back. That ensures that nobody is disadvantaged because they cannot afford the price of a telephone call.
