Israeli Prime Minister Benjamin Netanyahu's wife was questioned by police on Wednesday night as the family faces mounting pressure over graft allegations.

Sara Netanyahu was interrogated by police who are investigating claims that the family received lavish gifts from wealthy businessmen, Israel Radio reported.

The prime minister himself was questioned twice by police last week regarding the allegations, along with claims he had tried to cut a deal with a media mogul in 2015 in return for positive pre-election coverage.

Netanyahu insists nothing will come of the investigation but faces mounting public calls for an indictment as more details of the case emerge.

Israel's Channel 10 television network on Wednesday quoted an unnamed official in Netanyahu's Likud party as saying "the Netanyahu era is coming to an end".
