That’s up from a month ago, when it was less than 53%, and there’s been a general coalescing of support for the government in a number of opinion poll surveys since Sanna Marin became prime minister in December.
Marin’s Social Democrats are elevated to second place in the new poll at 17.1%, behind the Finns Party whose popularity has fallen by 0.8% since the last Helsingin Sanomat.
The National Coalition Party has dropped slightly to third place and 16.9%.
The Greens are up marginally in fourth place; and there’s no change for the Centre Party stuck on 12%.
For other smaller parties there’s small gains for the Left Alliance up to 8% and for the Swedish People’s Party up to 4.4%.
The Christian Democrats also say a marginal 0.1% increase while Movement Now Liike Nyt is unchanged from last month’s poll at 1.9%.
The survey was conducted by Kantar TNS between 15th February and 13th March – before the government announced its extensive emergency measures to tackle the coronavirus pandemic.
A total of 2,234 people were interviewed for the survey, a representative sample of voters aged 18 and over from across Finland, excluding Åland.
The opinion poll has a margin of error of 2.1 percentage points for the largest political parties.
