"The law will provide automatic adjustment of emoluments every five years based on inflation," Mr Jaitley said as he presented the Budget 2018 proposals in the Lok Sabha.
Mr Jaitley's decision to include a salary hike for President Ram Nath Kovind, Vice President Venkaiah Naidu, Governors and Members of Parliament is unusual because their salaries and allowances are governed by different laws.
The revised emoluments for the President would go up from 1.5 lakhs to 5 lakhs, for the Vice President from 1.25 lakhs to 4 lakhs and for governors, from 1.1 lakhs to 3.5 lakhs. The hike would address the anomaly that has existed after bureaucrats got their hikes: President Ram Nath Kovind has a lower take home salary than his key aides.
"There has been considerable public debate with regard to emoluments paid to Members of Parliament. The present practice allows the recipients to fix their own emoluments which invites criticism. I am, therefore, proposing necessary changes to refix the salary, constituency allowance, other expenses payable to Members of Parliament with effect from April 1, 2018," Mr Jaitley said.
Mr Jaitley did not specify the extent of the hike that lawmakers - members of the Lok Sabha and Rajya Sabha - would get. But changing the law to index their salaries to the price index is a huge concession.
Lawmakers have been demanding for years that an independent body should be set up, quite like the pay commission for bureaucrats, which gives them a hike.
Apart from other allowances and perks, Members of Parliament are paid a monthly salary of Rs 50,000, almost half of what the President gets.
In 1951, India's first President's salary was ten times the salary of lawmakers and ministers. But over the year, this difference has narrowed down
