An Italian couple are to become the world's oldest divorcees, after the 99-year-old husband found that his 96-year-old wife had an affair in the 1940s.

意大利一对夫妇将成为世界上最高龄的离婚者。99岁的丈夫日前发现自己96岁的妻子在上世纪40年代有过一段婚外情。

The Italian man, identified by lawyers in the case only as Antonio C, was rifling through an old chest of drawers when he made the discovery a few days before Christmas.

Notwithstanding（尽管，虽然） the time that had elapsed since the betrayal, he was so upset that he immediately confronted his wife of 77 years, named as Rosa C, and demanded a divorce.

Guilt-stricken, she reportedly confessed everything but was unable to persuade her husband to reconsider his decision.

She wrote the letters to her lover during a secret affair in the 1940s, according to court papers released in Rome this week.

The couple are now preparing to split, despite the ties they forged over nearly eight decades – they have five children, a dozen grandchildren and one great-grand child.

The discovery of the letters was the final straw for a marriage which had already run into difficulty – 10 years ago the husband briefly¹ left their house in Rome and moved in with one of his sons, only to return a few weeks later.

The Italian press attributed the acrimonious²（严厉的，辛辣的） split to the couple's southern blood – he is originally from Olbia in Sardinia, while his wife was born in Naples.

The couple met during the 1930s when Antonio was posted as a young Carabinieri officer to Naples.

The case appears to set a new record, at least for the age of the oldest protagonist³（主角，主演） – the previous oldest couple to divorce were Bertie and Jessie Wood, both aged⁴ 98, from the UK.

The pair ended their 36-year marriage in 2009 when they were both two years away from their 100th birthdays.

They got married in Elstree, Hertfordshire, in 1972, having both ended previous marriages, before moving to Falmouth, Cornwall four years later.
