Modi, who is set to spend his weekends in the national capital in the coming days to devote time to strategising for the elections, held a long meeting at Singh's residence.
Party sources said Modi wants the central BJP unit to be more involved in his programmes, including organisation of his rallies across the country. Till now this task has been handled by his core team based in Gandhinagar.
The Gujarat Chief Minister will also address a rally in Delhi on September 29.
Other than the organisation of rallies and the increased involvement of the central team in this exercise in the coming days, the allocation of specific tasks to 20 sub-committees formed under the Election Campaign Committee was also discussed.
RSS is also keen that it should be involved in organising Modi's rallies to make them a success.
