There is no doubt that President Kaczynski had often been a controversial and polarising figure in Polish politics.
Fabian Executive member and former Europe Minister Denis MacShane MP who has close links with Poland has praised Kaczynski as a "Polish patriot" and says that every friend of Poland would be shocked and saddened by his death.
"This awful tragedy takes away a true son of Poland who sought always to uphold the honour and stature of the Polish nation and people as he saw them.
He was a stalwart of the independent Solidarnosc trade union movement and fought to restore democracy to Poland in the 1980s.
As president he was brave when he risked his life by flying to Georgia in 2008 to show solidarity with the Georgian people when they faced the land-sea-air invasion by Russia.
He reached out to the Jewish community and worked with Poland's chief Rabbi Michael Schudrich.
Last week there was an important moment when Russia's prime minister Putin finally acknowledged Russian guilt for the crimes of Katyn. Poland is more than ever integrated into Europe. The exchanges of people, goods, ideas and culture between Poland and Britain is stronger than ever.
President Kaczynski was a Polish patriot and his tragic death hurts and hits all Poles and friends of Poland."
