Telugu Desam Party (TDP) MP Rayapati Sambasiva Rao on Friday offered his kidney to External Affairs Minister Sushma Swaraj, who is suffering from kidney failure and on the lookout for a suitable donor.

In a letter to Sushma Swaraj, Rao said: "I am very sorry to hear about your health problems and that you have been diagnosed with renal failure. As AIIMS doctors have advised you for the renal transplant at the earliest, Madam I shall be very grateful (if) you kindly accept my offer for donation of my kidney to you for transplant."

The 73-year-old MP hails from Narasaraopet constituency in Andhra Pradesh.

According to AIIMS doctors, the search for a donor is on and the date for transplant will be fixed once a donor is arranged for the minister.

The minister, who was admitted on Nov 7, is undergoing dialysis whenever required.

On Wednesday, Sushma Swaraj, 64, tweeted about her health condition: "I am in AIIMS because of kidney failure. Presently, I am on dialysis. I am undergoing tests for a kidney transplant. Lord Krishna will bless."

The team of top doctors for the treatment of Sushma Swaraj includes, Head of Endocrinology Nikhil Tandon, Head of Pulmonary Medicine Randeep Guleria, Chief of Cardio Thoracic and Head of Nephrology Sandeep Mahajan.
