A junior lawmaker from the ruling Liberal Democratic Party on Thursday indicated her intent to resign following allegations that she physically and verbally attacked one of her secretaries, an LDP source said.

The move by second-term Lower House lawmaker Mayuko Toyota comes as campaigning starts Friday for the Tokyo Metropolitan Assembly election, which will take place under the cloud of favoritism allegations directed at Prime Minister Shinzo Abe, who also serves as head of the party.

"We want to do something about this quickly," a senior LDP member said Thursday.
