On several occasions there were serious discussions if a person is politically eligible if he/she has been finally convicted (final decision). The typical example is the current (2017) Romanian President of Chamber of Deputies, Liviu DRAGNEA.
Dragnea was convicted of electoral fraud in 2015:
A senior Romanian minister was convicted on Friday of electoral fraud over a 2012 attempt to impeach a president and political rival, a judgment that dealt a blow to Prime Minister Victor Ponta’s efforts to demonstrate to the EU a hard line on graft.
Its case was brought to public attention once more, when a Romanian National Anticorruption Directorate investigation linked him to EU funds fraud:
The Romanian National Anticorruption Directorate (DNA) has accused Liviu Dragnea, the leader of the Romanian Social Democrat Party (PSD), of fraud with European Union (EU) funds, of creating an organised criminal group, and of misusing his position for personal gain. Eight more persons have been placed under criminal prosecution on similar charges.
The contribution of the European Anti-Fraud Office (OLAF) to this outcome has been emphasised by the DNA.
Dragnea is an elected deputy since the end of 2016 and also President of Chamber of Deputies ("the third person in the country").
Some argue  that this case (having a high official already convicted) is unique (in a bad way) in EU and that he should resign. Even the President commented upon this case.
I am interested in the so called uniqueness of the case within European Union.
Question: Were/are there any high officials (heads of parliament chambers, prime ministers or president of the state) that have been elected/appointed after being convicted? (EU countries only)
