The Cabinet Committee on Parliamentary Affairs today has recommended the dates for parliament's winter session.
This could fail to relent the Opposition which has been alleging that the government wants to "run away" from facing the heat on key issues during Gujarat polls, which end on December 14, a day before the session commences now.
25th and 26th December will be Christmas holidays.
The letter said, "We seek to draw your attention to the inordinate delay by the government in convening the Winter Session of Parliament without ascribing any justification for doing so".
When asked if MPs would be asked to be present on January 1, Mr Kumar said they should be present on all working days, including New Year's Day. The meeting was chaired by Union Home Minister Rajnath Singh.More news: Chris Pratt Pets Baby Raptor In 'Jurassic World: Fallen Kingdom' Teaser

Earlier this week Congress president Sonia Gandhi had launched a scathing attack on the Centre over the Winter Session.
Following criticisms from the Opposition regarding the delay in the Winter Session of Parliament, which generally begins in mid-November, the government has confirmed that the winter session will take place from December 15 to January 5 with a total of 14 sittings.
Finance minister Arun Jaitley had also commented that the Winter Session schedule would be such that it would not overlap with the assembly elections, and it would be a "regular" session.
Kumar alleged that the Congress was levelling allegations out of desperation and frustration as it would be routed in assembly elections in Gujarat and Himachal Pradesh.
