Maria Rosaria Boccia, businesswoman and former lover of ex culture minister Gennaro Sangiuliano, on Wednesday said she was pulling out of regional elections in Campania after receiving her second notice of investigation in just over a year.

Boccia, whose affair with Sangiuliano led the minister and member of Premier Giorgia Meloni's Brothers of Italy (FdI) party to resign, wrote to the leader of her small rightist Popular Alternative (AP) party, Terni Mayor Stefano Bandecchi, to tell him about her decision.

Boccia was leading the AP ticket in Campania elections on November 23-24, while Rai journalist and Paris correspondent Sangiuliano was at the head of the FdI slate.

"Dear President," she wrote, "yesterday evening I received my second notice of investigation in just over a year.

This news deeply hurt me.
