The president of Norway's parliament, Eva Kristin Hansen, resigned from her post late on Thursday, amid uproar about a taxpayer-funded flat she keeps in Oslo.
Hansen told Norwegian broadcaster NRK that she thought it was untenable for the parliament to have a president who was being investigated by the police.
She said she had contacted her party leader and parliamentary group leader to say she would resign as president of the legislature.
The 48-year-old came under fire after it was revealed that she may have unjustly had a parliamentary flat in the Norwegian capital.
Hansen has owned a house near Oslo with her husband for years. However, she was registered in Tromsoe, which is why she was entitled to a commuter apartment.
Hansen claims to have misunderstood the rules - which appear to have caught out a number of Norwegian politicians.

In September, Family Minister Kjell Ingolf Ropstad resigned after it emerged that he was still registered with his parents, but was in fact living with his family in Oslo.
On Thursday, the public prosecutor's office announced that six members of parliament with commuter residences were under investigation.
Investigators are looking into possible fraud or other offences.
Hansen assumes that she is one of those people facing a probe.
