New Delhi: Vowing to bring BJP back into power in Delhi where it has lost three consecutive assembly elections, newly appointed state BJP President Vijay Goel on Sunday said the Sheila Diskhit government will be dethroned in the upcoming polls as people were fed up with it. "There is no challenge for me, I am the challenge for Congress. Give me 200 days, I will give you government in Delhi," he said while addressing party workers at a function here.
