The National Assembly president Richard Ferrand, a close ally of President Macron, was put under formal investigation in a financial impropriety case. In a statement on 12 September the assembly said that Ferrand, who denies any wrongdoing, would defend himself and was confident the case would be dropped. The previous day he was questioned at length by investigating judges. The situation is an embarrassment for Macron, and could bring renewed scrutiny to his promise to clean up French politics. Under French law, being put under formal investigation means there is ‘serious or consistent evidence’ that points to probable involvement in a crime. Ferrand was investigated for fraud before, and at that time he resigned as a minister. The latest probe relates, like the previous one, to his management of a health insurance company in Brittany.
