David Cameron, Prime Minister of the UK
George Papandreou, Prime Minister of Greece
For those in politics and government, Davos has been a celebrated stage for decades, serving newcomers and veterans alike.
For Cameron, like others before him, the meeting offers a global debut for the UK's first Conservative Party Prime Minister of this century.
For Papandreou, it's a easy opportunity to show leadership, put a human (and brave) face on the Greek drama and talk to private investors, NGO chiefs and government leaders alike.
