<h1>Parliament's Budget Session Starts Jan 31; Union Budget Presentation on Feb 1 Amid Opposition Concerns Over Election Timing.</h1> The Budget session of Parliament is set to begin on January 31, with the Union Budget likely to be presented on February 1. President Pranab Mukherjee has summoned the Rajya Sabha, and a similar notification is expected for the Lok Sabha. The session will start with the President's address and the pre-budget economic survey. This year marks the end of the separate railway budget, as its estimates will be included in the Union Budget. Opposition parties have objected to the budget's timing before state assembly polls, fearing it may influence voters, and have approached the Election Commission for intervention.
