The study tried to understand whether the relations have aided a smooth implementation of the budget in Nigeria focusing on the fourth Republic. The aim of the study includes to understand the nature of executive-legislative relations in Nigeria from 2007 to 2017, articulate the factors affecting legislative-executive relations in the course of budget implementation in Nigeria and assess whether legislative-executive relations impact on budget implementation in Nigeria. From available literature, the study revealed that the nature of Executive-Legislative relations in Nigeria has not been cordial. Furthermore, the study also showed that sectional interest and power tussle are factors affecting Executive-Legislative relations in the course of budget implementation in Nigeria. Finally, the study revealed that executive-legislative relations have no meaningful impact on budget implementation in Nigeria. Against this backdrop, the study recommended inter-alia that there should be proper definition of the constitutional roles of the executive and the legislature to avoid unnecessary fiction between the various arms of government. As such, the independent of the various arms should be ensured through constitutional provision to avoid the consistent executive domination of not just the legislature but also the judicial. Also, severe punishment should be reserved and enshrined in the constitution against persons caught promoting sectional interest above national interest.
