Mustapha also said the preparation for the 2019 general elections, expected to commence at the end of February, would also pose a challenge to the budget implementation.
He noted that serious government business would likely end by November when political parties would commence campaigns and conduct primaries.
The SGF appealed to the National Assembly to pass the budget as soon as possible to avoid possible poor implementation.
Mustapha spoke when he appeared before the Senate Committee on Federal Character to defend the 2018 budget of his office.
He said: โI will make an appeal that the 2018 budget must be passed on time. We do not have time. If you consider the time left for us as politicians and in line with the timetable released by INEC, you will realise that we have till November 2018 to do what we have to do.
โBy then, politicians will be engaged in political activities. There will be no time. I am appealing that we pass this budget on time. This is the last budget we will have to deliver on the dividends of democracy. For those of you coming back, promises will not work. What will work will be the scorecard.
โI am begging that it should be passed as quickly as possible. I am also appealing to the executive arm to appear for budget defence. Intense political activities will begin this February and as public officials, we have to quickly deliver.โ
