Tens of thousands took part in a march through Naples itself, and there were also protests in other towns and cities.

The action was organised by the main Trade Union Federation, which wants more jobs created and a campaign against organised crime.

The Federation is threatening a national strike unless the government takes urgent measures to deal with both problems.

Among the crowd that made its way noisily through the streets of Naples were local businessmen, students, politicians, priests and the mayors of other cities facing similar problems.

Quarter of the workforce unemployed

With 26% unemployment, Naples is a symbol of the under-development of Southern Italy.

The centre-left government is being accused of not maintaining its promises to the region.

A government aid package announced on Tuesday has been dismissed as inadequate as it consists largely of funds assigned several years ago but never spent.
