Italy’s centre right must push for reform of the justice system or seek new elections, former Prime Minister Silvio Berlusconi told lawmakers from his People of Freedom Party, according to a source at the meeting yesterday.

“If there is no reform of the justice system, we are ready for new elections,” he told the meeting, according to the source, who spoke on condition of anonymity.

On Thursday a court upheld a conviction for tax fraud against Berlusconi, threatening both his position as centre-right leader and the stability of Italy’s fragile coalition government.

Italy’s fragile coalition government, already struggling to contain deep divisions over tax and economic policy, woke up to a whole set of new problems yesterday after Silvio Berlusconi’s conviction for tax fraud was upheld by the supreme court.

Consequently just three months after centre-left Prime Minister Enrico Letta took office at the head of an uneasy alliance with Berlusconi’s People of Freedom party (PDL), Italy, the euro zone’s third largest economy, is again mired in uncertainty.

Letta repeated yesterday that Italy must have a stable government, saying the last thing it needs is to be worn down by partisan battles.

The 76-year-old billionaire and his supporters have reacted angrily to his conviction and prison term, the first definitive sentence he has received in dozens of trials during his two decades in politics.

While he is unlikely to spend any time in jail due to his age, the verdict was an unprecedented blow and he could lose his seat in Parliament within weeks with a vote on expelling him from the Senate likely in September.

He has declared he will continue his political activities under the Forza Italia (Go Italy!) name of his first party and press for a reform of the justice system, with speculation growing that his daughter Marina may succeed him as party leader.

So far he has given no indication of wishing to bring the government down and pitch Italy into fresh elections, but the already dim prospects of significant reforms to revive Italy’s stagnant economy and cut its massive debt have receded further.

Agreement over thorny issues such as privatisations due in the autumn or the much-disputed IMU property tax which Berlusconi wants to scrap but which would blow a hole in already strained public finances will be difficult.

“It depends on the PDL,” deputy Economy Minister Stefano Fassina, from Letta’s centre-left Democratic Party (PD) said.

“It’s not something that can be settled in the next few hours but over the next few weeks, we’ll have to settle the IMU issue and on an issue like this, it can’t just be about Berlusconi’s personal interests,” he said.

Problems just as serious could come from Fassina’s own fractious camp, with many in the centre-left unhappy at the prospect of remaining in alliance with a convicted tax evader. To add to Letta’s problems, Matteo Renzi, the ambitious young mayor of Florence, is widely expected to mount a bid to lead the party.

Letta himself said that the situation was “politically very delicate” and he called on all sides to show responsibility in the interests of the country.
