The announcement comes in light of the investigation into Roman Abramovich's Portugese citizenship

The leader of the Jewish community in Portugal's northern city of Porto responsible for issuing a document that allowed Abramovich to get Portuguese citizenship last year has been detained.
Thousands of Israeli Jews have been granted Portuguese citizenship since the law was passed in 2015.
