The new investigation will be launched less than six months after the former presented its proposals.
It had had four months to find out what needed to be done on and around Arlanda to develop the airport and the conditions for Arlanda to take over the operations that currently exist in Bromma.
On that basis, the government could then quickly make a decision to start a closure of Bromma.
Investigator Magnus Persson estimated that the government could make a decision on this as early as 2022 and a phase-out would then be made in three to five years.
Eneroth then said that the government's goal is to close down Bromma and concentrate traffic to Arlanda.
- It would provide better accessibility, better basis for international flights at Arlanda and also free up land and space at Bromma for housing, Eneroth said when the previous investigation was presented in August last year.
But a majority in the Riksdag, led by the Moderates, protested loudly and promised to tear up a decision to close down in the event of a change of power.
The government must beware of hasty decisions in the middle of a pandemic, was a heavy message.
Just before Christmas, when a new government, without the Green Party, had taken office, Eneroth announced that there would be a new investigation and that the government wanted support in the Riksdag for what would happen to the two airports.
But the goal is still, said Eneroth, to secure capacity and adapt Arlanda so that Bromma can be closed down.
