He also said though he does not feel comfortable about shifting to Delhi, he will take up the responsibility "if nation requires" his services.
"Party President Amit Shah spoke to me in the morning and asked me to accept any assignment that would be given by the Prime Minister," Parrikar told reporters.
However, he did not disclose whether Prime Minister Narendra Modi had offered him the defence portfolio during their meeting yesterday.
Parrikar said if any offer had to come, it would have to be before November 9, when union cabinet would be expanded.
"The party would not have asked me (to accept the offer) if they (top BJP leaders) had not interacted with the Prime Minister," he added.
Parrikar, who led BJP to victory in the 2012 Assembly polls, said he was not comfortable about having to shift to the Centre.
"One reservation (about moving to Delhi) is because I have been elected for a five-year term with a popular mandate. My feeling is unless I complete the term it is not right on my part to leave mid-way. If I get an offer from the Prime Minister, then I will let you know what are my reasons for accepting the offer," he said.
Parrikar said he would be meeting BJP MLAs tomorrow to brief them about the development. He, however, refused to say anything about who would be his successor.
