A call to establish a National Slavery Remembrance Day will be heard in the House of Commons later.
Mrs Ellman will also push for a campaign against people trafficking
The plea will come from Louise Ellman, MP for Liverpool Riverside, who will say the city was a slave trade centre in the 18th and 19th century.
"Since then the city has been at the centre of exposing the shameful history of slavery because of the work done by Liverpool's museum," Mrs Ellman said.
She will also push for a campaign against the trafficking of women.
She will say the smuggling of women for sexual exploitation is a new slavery.
