Italian vote points to impasse

Partial results from Italy's election suggest the houses of parliament may split between left and right, causing new anxiety in the eurozone.

Projections suggest Pier Luigi Bersani's centre-left bloc has a narrow lead in the lower house while Silvio Berlusconi's centre-right is ahead in the powerful Senate.

A protest movement led by comedian Beppe Grillo surged into third place, as Gavin Hewitt reports.
