Alexander Solzhenitsyn has received a very good obit in the Guardian (h/t Jogo, who quite rightly says "I daresay many of its older readers cannot truthfully claim always to have loved and respected him"). The Indy publishes his last interview.
Predictably, the Stalinists and neo-Stalinists highlight his antisemitism and reactionary nationalism - Lenny here in the UK, or Andrew Austin in America, who calls the US prison system the American gulag (nearly as offensive in my mind as comparing it to the concentration camps).
For a more nuanced view, read Christopher Hitchens (of course) and Ross Douthat. They get a better measure of both his grandeur and his flaws.
