Kelvin Hopkins, the Labour MP suspended following allegations of sexual harassment, sent a younger female colleague a series of unsolicited love letters, according to new claims.
The 76-year-old, a former shadow minister, sent Labour’s Kerry McCarthy letters and cards commenting on her “very pretty” and “attractive” appearance in a periodic campaign of unwanted attention spanning 20 years.
Ms McCarthy, who is 24-years his junior, said she felt compelled to speak out following a Daily Telegraph investigation which unearthed allegations that he had sent "inappropriate" text messages and rubbed himself against Ava Etemadzadeh, a young party activist, after a political event.
She told the Telegraph: "I couldn't leave Ava to fight this alone when elements of my story are so similar."
Mr Hopkins, who is married, released a statement addressing the new accusations before they were published in the public domain.
He claimed the complaint had caused "immense personal hurt and utter dismay" and placed “unbearable stress” on him and his family.
Ms McCarthy, 52, a former shadow environment secretary, is the first MP to make specific claims of inappropriate behaviour since the Westminster scandal erupted.
She said she began receiving unsolicited attention from Mr Hopkins in the mid-1990s, when the pair were chairs of neighbouring constituency parties in Luton, but the most recent incident was less than two years ago.
She found his behaviour “upsetting” but did not report it in the past because she did not feel she had anywhere to turn.
However, she spoke out to support Ms Etemadzadeh, whose complaints to Nick Brown, the chief whip, with fresh information following an initial complaint over dealings with the MP in 2014 and 2015 led to his suspension last week.
“I don’t believe that I am the only one,” she added.
The Bristol East MP said that in 1994, when she was chairwoman of Luton North constituency Labour Party (CLP) and he chaired Luton South CLP, he invited her out for lunch, ostensibly to discuss political issues.
Shortly afterwards, he sent her a card saying: “My only reason for asking you out to lunch is because you are attractive, intelligent and charming.”
He added “PS: best to dispose of this once read!”
Ms McCarthy said: “That to me felt really intrusive.”
In a second note, Mr Hopkins enclosed a photograph of Ms McCarthy and described her as "pretty" before again asking her to dispose of it.
He also sent a postcard in an envelope, asking whether her employer specialised in "pretty, petite brunettes".
Ms McCarthy said she went to another lunch with Mr Hopkins because she found it awkward to say no. He sent a card afterwards suggesting it "would be nice to meet again".
On another occasion, Ms McCarthy said Mr Hopkins placed his hand on hers when she was not looking as she was getting out of a car.
A note sent in the run-up to the 1997 general election said: "You know I think you are lovely ... but I never see enough of you ... after May 1st perhaps ... K x"
The letters then stopped until her 50th birthday, by which time Ms McCarthy was an MP.
He sent two notes more recently on parliamentary notepaper, one of which said: “I dreamt about you last night. A nice dream.”
It went on: “Much time has passed but I do remember earlier times … and you remain a very attractive woman.”
Ms McCarthy said she believed Mr Hopkins knew his actions were wrong.
"I never responded in any way, I never gave him any encouragement in any way, I tried to keep my distance as much as possible," she said.
"I absolutely believe he knew this behaviour was unacceptable. It made me feel uncomfortable in his presence and was quite upsetting."

The allegations will only fuel the Westminster sexual harassment scandal, which has escalated dramatically this month.
Sir Michael Fallon resigned as defence secretary after admitting that his behaviour had fallen short of the standards expected of his post, Charlie Elphicke, Tory MP for Dover, was suspended and reported to the police over unspecified allegations and Labour MP Jared O'Mara lost the party whip amid an investigation into his behaviour.
In his statement, Mr Hopkins' took umbrage to the fact that Ms McCarthy had made her allegations public before allowing him a chance to respond through official channels.
"If Kerry McCarthy MP raises a complaint with the Labour Party in the normal and fair way, I will of course fully cooperate with any investigation,” he said.
"However I do ask, on my behalf and on behalf of all other individuals and their families dealing with allegations, that these matters are dealt with by proper due process and not by unfair, humiliating one-sided trial by media.
"I am a 76-year old man and the stress this has caused me and my family is unbearable.
"All I ask for is proper due process and not to be convicted and vilified by the press before the details of the allegations are even investigated and put to me properly if they need to be."
Mr Hopkins "categorically denies" any inappropriate conduct in relation to Ms Etemadzadeh, now 27.
He was reprimanded when the original complaint was made by then chief whip Dame Rosie Winterton but was appointed shadow culture secretary in 2016.
