The lawyer for Liberal MP Ruby Dhalla says allegations of nanny abuse against his client are part of an orchestrated attempt to destroy her reputation and ruin her political career.

"There is no truth to them," said lawyer Howard Levitt, seated next to his client at a news conference in Brampton, Ont., on Friday.

"The only question is, who's really behind them and who orchestrated or assisted or enabled these former employees of her brother to suddenly come forward one year after the last of them worked providing care for her mother?"

Two former caregivers who worked at the Dhalla home in Mississauga, Ont., last year say they were told to do extra work, like cleaning the family's chiropractic clinics and washing cars.

The immigrant nannies -- Magdalene Gordo and Richelyn Tongson -- also say their passports were seized and that they were underpaid for their work. Another caregiver has also come forward with similar allegations.

Levitt stated: "whoever has decided to target her has made a grievous error."

Dhalla denied those claims on Friday and said that the "false and unsubstantiated" allegations have been troubling and hurtful to her family.

"Anyone that has ever entered our home has always been treated with love, with care, with compassion and respect," Dhalla said.

The embattled MP added that she has asked the ethics commissioner to probe the allegations and that the truth will exonerate her.

"Anyone that has ever entered our home has always been treated with love, with care, with compassion and respect," Dhalla said.

"As such, the allegations that have been brought forward against myself have come as a big shock and have been devastating to both myself and my family, friends and supporters."

Dhalla added she has always been a champion of immigrant women and their rights.

While Dhalla has stepped down from her role as the Grits' multiculturalism and youth critic, Liberal Leader Michael Ignatieff said his office has provided her with advice and support throughout the affair.

"I support her desire to get to the bottom of this and we are giving her advice and counsel," Ignatieff said in Toronto Friday.

"We're looking forward to full and complete disclosure on every side of this unfortunate circumstance."

While Dhalla has now spoken publicly for the first time about the allegations, her lawyer deflected many of the scandal's most pressing questions and referred them to the politician's brother, Neil Dhalla.

Reaction spreads

"They appeared to be trying to pin this ... on Ruby Dhalla's brother," said CTV's Rosemary Thompson, speaking from Ottawa on Friday.

Thompson added that the reaction on Parliament Hill has thus far been mixed, with some colleagues like fellow MP Judy Sgro openly supporting Dhalla.

"There are others in the party, some that have worked for her in the past, that have been more critical, but are doing it anonymously," she said.

Agatha Mason, executive director of Intercede, said the federal program that brings in foreigners to work as live-in caregivers is "broken" and needs to be reformed.

"If we were to listen to all of the stories that the caregivers have told us and mentioned over the years, it's really a shame," she said at a press conference in Toronto Friday.

"Imagine yourself a caregiver: you wash, you cook, you look after children, you serve the people who employ you, and you go in a room because you're not good enough to sit at the table."
