New Delhi: Former PM Manmohan Singh was admitted to the All India Institute of Medical Sciences (AIIMS) in Delhi on Wednesday evening after he complained of weakness following a fever, sources said.

They said the 89-year-old had a fever on Monday and had recovered from it, but turned weak and is currently on fluids.

In April this year, Singh was admitted to the hospital due to the coronavirus infection.

Pranav Jha, Congress secretary in-charge of communications, said Singh’s hospitalisation was due to “routine treatment”.

Prayers for the early recovery of the former prime minister poured in from a host of leaders across party lines.

"Praying for quick recovery and good health of former Prime Minister Dr. Manmohan Singh Ji who has been admitted to AIIMS," said Punjab Chief Minister Charanjit Singh Channi.

Union minister Mukhtar Abbas Naqvi, former Union minister Ashwani Kumar, Congress leader Mukul Wasnik and Shiv Sena leader Priyanka Chaturvedi also wished Singh a speedy recovery.

Among others, former Punjab chief minister Amarinder Singh, Congress leader Abhishek Singhvi and NCP's Nawab Malik also prayed for the ex-prime minister's good health.
