After it became clear that the Congress was heading for a massive victory, Chief Minister Raman Singh submitted his resignation to the governor.
Singh told reporters that he accepted the responsibility for the loss, refusing to pass the buck to the BJP's national leadership.
"The election was solely contested on a state agenda and it was not related to Delhi. We will sit with the party workers and analyse the defeat in detail.
"This will not reflect on the 2019 Lok Sabha election," he said.
In the 2013 Assembly polls, the BJP had won 49 seats, the Congress 39, while one seat each was bagged by the BSP and an Independent.
