The former head of a school operator at the center of a scandal involving its discounted purchase of state land was granted bail Friday along with his wife, about 10 months after being arrested on suspicion of fraudulently receiving public subsidies.

The Osaka District Court rejected a complaint lodged by prosecutors against its decision on Wednesday to allow Yasunori Kagoike, the 65-year-old former chief of Moritomo Gakuen, and his 61-year-old wife Junko out on bail.

The couple came into the spotlight over the operator's purchase of the state land in Osaka Prefecture to build an elementary school, of which Prime Minister Shinzo Abe's wife Akie was named honorary principal.

The government offered the land at less than a seventh of the appraisal price, ostensibly to cover the cost of removing waste buried at the site.

Akie Abe resigned from her post after the controversial deal was revealed. Kagoike has claimed that as an acquaintance, he was given special treatment in the deal.

The prime minister has denied that either he or his wife was involved.

The Kagoikes have been held at the Osaka detention center since their arrest on July 31, 2017, on unrelated charges, including defrauding the central and local governments of 170 million yen ($1.55 million) in school subsidies.

At a press conference held Friday evening, Kagoike said their detention was politically motivated and challenged Abe's version of events. "As a statesman, he should tell the truth fair and square," he said.

While Kagoike declined to discuss his own case, he called the charges against his wife, who began sobbing at one point in the press conference, "false accusations."

While he is likely to admit that he did apply for the local governments' subsidies, his wife plans to deny having deep knowledge of details of the subsidies, according to sources close to the matter.

As for subsidies from the central government, the Kagoikes are expected to argue against the fraud charges.

The court rejected the couple's previous request for bail last November. A second request was filed earlier this month.

The couple's lawyer said bail of 8 million yen was set for Kagoike and 7 million yen for his wife.
