A day after a purported audio tape -in which she is heard proposing a rally with the bodies of Cooch Behar firing victims- surfaced, West Bengal Chief Minister Mamata Banerjee on Saturday alleged that her phone is being tapped and said she will order a CID probe into it.

Addressing an election rally here, she accused the BJP of being involved in the conspiracy as the saffron party "cannot match" the ruling Trinamool Congress'' campaigning on development programmes.
