Brown interrupted by own mobile

Gordon Brown: 'I'm afraid that's my phone'

Gordon Brown was interrupted by his own mobile phone while addressing political and business leaders in Davos.

The prime minister's mobile rang twice during his speech at the World Economic Forum, leading Mr Brown to note that the caller was "persistent".

But he disappointed his audience by not disclosing the caller's identity.

The incident revealed that Mr Brown uses an old Nokia ringtone on his phone - made famous by comedian Dom Jolly on his satirical show Trigger Happy TV.

Shortly into his speech about the global economic crisis in Switzerland, a phone started ringing.

The prime minister admitted: "I am afraid it is my phone."

When asked by a reporter who was calling, he replied: "I am not telling you."

When the phone rang again a few seconds later, the prime minister turned it off.

In his speech, Mr Brown stressed the world must "come together" to deal with the stark economic challenges it faced.
