A Conservative MP could face an investigation over her failure to declare cash donations after a complaint was made to a Westminster standards watchdog.
The office of the Parliamentary Commissioner for Standards today confirmed it had received a letter of complaint on Charlotte Leslie.
A spokeswoman for the independent officer, Kathryn Hudson, said the letter would be looked at before a decision is taken on whether or not t o begin an inquiry.
The MP for Bristol North West offered her "heartfelt apologies" in the House of Commons last week for failing to declare cash donations in the register of members' interests.
She told MPs she had asked three written parliamentary questions, made her maiden speech, one intervention and asked a question to a select committee witness without declaring a "potentially relevant interest" on the register.
Ms Leslie said the donations to her local Conservative Party had already been declared to the Electoral Commission when they were discovered not to be on the MPs' register last August.
Her office said the "potentially relevant" donations are £12,000 linked to the Bristol Port Company and £2,500 from Theodore Agnew.
Ms Leslie, who w as elected in May 2010, also told the Commons she had not personally benefited financially.
She added s he took full responsibility for not submitting the details in a "timely fashion" despite seeking to have extra administrative support as a result of being registered dyslexic.
A spokeswoman for the Parliamentary Commissioner for Standards told the Press Association: "We have received a letter of complaint about Charlotte Leslie.
"We will look at that letter and decide whether or not to begin an inquiry."
The spokeswoman was unable to provide more details about the complaint.
Wayne David, Labour MP for Caerphilly, told the BBC last week he planned to refer Ms Leslie to the Parliamentary Commissioner for Standards.
But Mr David confirmed today he was not the person who sent the letter of complaint.
