The Bharatiya Janata Party today slapped a show-cause notice on its suspended MP Kirti Azad, asking him to explain within 10 days why he should not be expelled from the party for 'indiscipline' and 'anti-party' activities.

BJP sources said the notice is a standard follow-up to suspension of a party leader and a decision on expulsion of Azad, who has continued to attack Finance Minister Arun Jaitley over the Delhi cricket body affairs, will depend on his reply.

Sources close to the three-time Darbhanga (Bihar) MP said he was 'ready' with his reply and will send it to the party headquarters tomorrow.

Party leader Subramanian Swamy, who had earlier questioned his suspension, has 'vetted' his reply, they said.

An undeterred Azad has continued to target Jaitley over the alleged corruption in Delhi and District Cricket Association and also attacked party MP and Board of Control for Cricket in India secretary Anurag Thakur besides Rajeev Shukla of Congress over alleged irregularities in cricket administration.

The show-cause notice spells out his 'anti-party' activities, including his demand for a Central Bureau of Investigation probe in the Lok Sabha into the DDCA affairs and his continued allegations even though the BJP and the government had refuted similar charges levelled by opposition parties like the Congress and the Aam Aadmi Party.
