West Bengal Chief Minister Mamata Banerjee, who is at the forefront of talks for an anti-BJP federal alliance for 2019 general elections, on Wednesday shot down DMK chief MK Stalin's comment favouring Congress president Rahul Gandhi as opposition's prime ministerial face. The time was not right for such discussions, she said. "I am not alone (in the proposed alliance). We are working together. So whatever all the political parties, who have come together will decide, we will accept that. Now is not the right time. Let us hope for the day when there will be a good change," Ms Banerjee told reporters at the state secretariat in Kolkata.
