In an election that marks a turning point in India's politics, one of the most remarkable stories is the BJP's record return to power in Uttar Pradesh. For the first time in three decades, a party has been re-elected in UP, India's most politically important state, which is a bellwether for national elections. The BJP won four out of five states; the Aam Aadmi Party (AAP)'s "tsunami" in Punjab is the other big story of today's election results.
