"Russia will not hand over dispatchers to Poland in the Kaczynski case, this is prohibited by the Russian Constitution," RIA Novosti quoted him as saying.
He also recommended to Poland “to close the case on this”.
Earlier, the Polish prosecutor's office demanded the arrest of three air traffic controllers who worked at the Smolensk-Severny airfield on the day of the crash of the Tu-154 Kaczynski.
Kaczynski's plane crashed in 2010 while landing at Smolensk-Severny airport.
96 members of the Polish delegation were killed.
According to the Interstate Aviation Committee, the immediate cause of the crash was the decision of the crew not to leave for an alternate airfield, but systemic - shortcomings in flight support and crew training.
