B N Manjunath Reddy, the councillor from Madiwala was elected Mayor, after Congress won 131 votes in the mayoral polls. Hemalatha Gopalaiah of the JD(S) will be the Deputy Mayor.
Hectic parleys on the eve of Bengaluru mayoral poll saw the Congress and JD(S) thrash out details of power sharing within the urban civic body.
The BJP had won 100 wards out of 198 in the polls held on August 22. Congress had bagged 76, JD (S) bagged 14 and others eight.
Senior BJP leaders including Ananth Kumar, Suresh Kumar, Ashoka, Ashwath Narayan and Venkiah Naidu walked out of Council hall after casting their votes.
Union Minister Ananth kumar said Congress had behaved in a very undemocratic way. "They have respected people's wishes. This is a setback for democracy." he added.
"Democracy is about numbers. We have no reservations about what happened," said the Congress' Veerappa Moily.
New mayor Mr Reddy is 52 years old and lists himself as a "social activist and active Congress worker." A corporator for many years, he has his task cut out - Bengaluru has big civic problems like nightmare traffic, bad roads, poor garbage disposal and polluted lakes.
Hemlatha of the JDS is the new deputy mayor.
Karnataka is ruled by the Congress. It snatched power in 2013 from a deeply fractured BJP that was also hit hard by corruption charges against important party leaders. Months later, in the national election, the BJP won 17 of the state's 28 seats, sweeping all three Lok Sabha seats in Bengaluru.
