Alexei Navalny, the most prominent critic of Russian President Vladimir Putin, has died in jail. Barred in 2018 from running in elections, he remained Mr Putin's most powerful political opponent.
He survived a novichok poisoning, after being treated in Germany. But still he chose to return to Russia knowing he would be arrested. He was just 47 when he died while serving a 19-year sentence on charges of extremism in a prison near the Arctic circle.
Today on Sky News Daily, Leah Boleto speaks with our Moscow correspondent Diana Magnay about Mr Navalny's life and how his death will have an impact on his supporters in Russia.
We'll also unpack Labour's win in two by-elections overnight with our political correspondent Rob Powell who is in Wellingborough, and what the results could mean for the next general election.
