Margaret Alva has resigned as an All India Congress Committee general secretary. Alva resigned in the  wake of her allegations over "sale" of party tickets in the Karnataka Assembly polls.

Alva, who is in-charge of the party in Mizoram, returned to Delhi [Images] from Aizwal late on Monday night and met A K Antony,chairman of the party's desciplinary committee and handed over her resignation to him.

This is the first time that Alva has made such an allegation. It is believed that Alva's son was denied a ticket during the state assembly elections which upset her and forced her to make the allegations.

Congress president Sonia Gandhi [Images], who was in Bhutan at that time, asked Antony to investigate and seek a clarification from the veteran Karnataka leader. When Antony met her, Alva offered to resign from the post of general secretary if the party did not give due weightage to her allegations and conduct a full scale probe.

According to party sources Alva is holding talks with Mayawati [Images] and former prime minister Deve Gowda. Senior party leaders conceded that Alva would be given a chance to explain before the party takes any decision.
