Arun Jaitley has told PM Narendra Modi that he would like to stay away from "any responsibility" in the Modi government's second term in office.

Writing to the prime minister, Jaitley cited health reasons for his decision. Jaitley said staying away from any responsibility will help him concentrate on his treatment and health.

Jaitley, who underwent a kidney transplant surgery last year and has been unwell for a large part of the last two years, posted the letter on his Twitter feed.

"I have today written a letter to the Hon'ble Prime Minister, a copy of which I am releasing," Jaitley said, posting an image of his letter to PM Narendra Modi.

In the letter, Jaitley said it had been an "honour" and a "learning experience" to be part of the Modi-led National Democratic Alliance government.

Jaitley said in the last year-and-a-half, he's had some "serious health challenges". "My doctors have enabled me to emerge out of most of them," Jaitley said, before placing his request that he not be given "any responsiblity" in the Narendra Modi government's second term.

In the letter, Jaitley mentioned that he had verablly told PM Narendra Modi about needing to stay away from any responsiblity "for some time" in the future.

"I am writting to you to formally request you that I should be allowed a reasonable time for myself, my treatment and my health and, therefore, not be part of any responsibility, for the present, in the new government," Jaitley said, adding that he would "undertake any work informally to support" the government or the party.

Arun Jaitley has been keeping unwell for a large part of the last two years of the Modi government's first time.

He took a three-month break from work last year after undergoing a kidney transplant surgery. Piyush Goyal served as the interim finance minister; Jaitley resumed work only in August 2018.

In January this year, Arun Jaitley unexpectedly left for the US for a medical check-up. The Interim Budget, which was unveiled on February 1, was presented by Piyush Goyal in Jaitley's absence.

Arun Jaitley posted the letter on Twitter a day before Narendra Modi takes oath as prime minister for the second time. The Bharatiya Janata Party won the 2019 Lok Sabha election by a landslide, crossing the 300-seat mark on its own -- a first for the saffron party.

Narendra Modi will take oath as prime minister on Thursday evening. Several other leaders will take oath to become minister in the new Narendra Modi cabinet.
