The centre has offered land to Manmohan Singh's family in the Rajghat complex to build a memorial for the former prime minister who died in December, government sources have told NDTV, adding that the plot is next to the memorial of Pranab Mukherjee, former Congress leader who was the president when Mr Singh was prime minister. The government is waiting for the family to build a trust and land will be allocated once it's formed, sources said. The government will provide Rs 25 lakh to the trust to build the memorial, they added.
