Differences within the BJP on the issue of providing reservations in promotion for SC and ST government employees intensified even though the party had supported the passage of the 117th Constitution Amendment Bill in Rajya Sabha earlier this week.

A day after BJP MP Maneka Gandhi said all party MPs from Uttar Pradesh were against promotion quota bill, the two party MPs-Lalji Tandon (Lucknow) and Varun Gandhi (Pilibhit) - asked the leadership to have a re-look into the matter.

Varun Gandhi wrote to party chief Nitin Gadkari, opposing the legislation saying that such a step will drive a wedge between sections of society.

Tandon said an all-party meeting should reconsider the matter.

On Friday, the last day of the winter session of Lok Sabha, the BJP refused  to back the measure, arguing that the original text had undergone changes and more time was needed to study it.

Led by LK Advani, senior BJP leaders Sushma Swaraj, MM Joshi and Rajnath Singh appear to favour that the bill,which was passed by Rajya Sabha, should be referred for a review by the Supreme Court.

Leader of opposition in Rajya Sabha Arun Jaitley had supported the bill after the government assured in the House that the rules under the law would ensure that merit was not affected in this regard.
