Italian Prime Minister Matteo Renzi has persuaded European partners to attend a meeting on jobs in Milan on Wednesday but he may struggle to get them to agree to do much more than show up. Originally presented as a summit and later downgraded to a “high-level conference”, the encounter is meant to help develop a response to the jobs crisis, especially among the young, that is hitting southern European countries particularly hard. The figures are particularly high in southern Europe and among young people, of whom about a quarter are unemployed.
