Donald Tusk, the European Council president, has been summoned for questioning this week by Warsaw prosecutors probing cooperation between Polish and Russian security services, according to reports.
“Mr Donald Tusk has been summoned as a witness in a case against former heads of military counter-intelligence services (SKW), who were charged with co-operating with intelligence services of another country without the required authorisation of the prime minister,” said Michal Dziekanski, a prosecutor, according to Reuters.
Poland’s niezalezna.pl website said prosecutors were probing improper cooperation between the SKW and Russia’s Federal Security Service, or FSB, the successor to the KGB.
The case first surfaced in Polish media in December.
Although the alleged cooperation took place without Mr Tusk’s authorisation and knowledge, the summons to appear as a witness may be seen in Brussels as a further attempt by Poland to embarrass him, after Warsaw failed last week in attempts to derail the former Polish premier’s re-appointment to a second term as European Council president.
The right-wing Law and Justice government had put forward Jacek Saryusz-Wolski, a Polish MEP, instead.
