IMF chief Lagarde urges global action as G7 meet

International Monetary Fund chief Christine Lagarde has urged "bold action" on the faltering world economy, ahead of a meeting of the Group of Seven richest nations.

The G7 is meeting in Marseille to consider a "co-ordinated response".

The two-day meeting comes after the Organisation for Economic Co-operation and Development raised fears of a global slowdown this year.
