The Prime Minister will address the nation at 8 PM on Doordarshan about the recent decisions on economic reforms, officials said.
He is likely to cite the difficult times facing the economy and emphasise that the steps were taken to push economic growth and generate employment.
The thrust of the Prime Minister's message is expected to be that the decisions were taken in the national interest.
In the Cabinet decision on Sept 14, Singh had said the step was intended to "bolster economic growth and make India a more attractive destination" for foreign investment.
"I believe that these steps will help strengthen our growth process and generate employment in these difficult times," he had said and sought support of "all segments of public opinion" for this.
The decision to go ahead with FDI in multi-brand retail has evoked angry reactions from Trinamool Congress which has decided to quit the UPA government.
UPA's outside allies like Samajwadi Party and JD-S as well as opposition parties are also agitated over the decision and had organised a nationwide bandh yesterday.
