OSLO, March 31 (Reuters) - Norway's public finances will face greater pressure in the future as the country's sovereign wealth fund is expected to grow more slowly, the country's centre-right government said in a long-term planning document on Friday.
"Investment returns are anticipated to moderate, and the oil price is not expected to return to previous highs. At the same time, an ageing population will increase spending on pensions, health, and social services," it said.
"Moving forward, the room for manoeuvre in the budget will be far less than what we have become accustomed to," it added. (Reporting by Terje Solsvik, editing by Gwladys Fouche)
