The Supreme Court today asked the Election Commission to proceed with its probe into the authenticity of former Maharashtra Chief Minister Ashok Chavan's spendings during the 2009 state assembly polls allegedly involving expenses on paid news.A bench of justices Altamas Kabir and J Chelameshwar, however, asked the Commission's counsel Meenakshi Arora to ensure that findings of the probe if completed are kept in a sealed cover.The bench passed the order on an application moved by former state minister Madhav Kinhalkar seeking direction to the Commission to complete the probe before June 10 as the present Chief Election Commissioner S Y Quraishi is due to demit office by that date.
