The Lesbian, Gay, Bisexual and Transgender campaign group 'Noise' organised today's march. It is campaigning for civil marriage for gay, lesbian, bisexual, and transgender people.
The Civil Partnership Bill, which was signed into law last month, provides marriage-like benefits in the areas of property, social welfare and tax.
However campaigners say the bill, while allowing a gay couple to pay taxes as a couple, does not provide legal protections for LGBT parents and their children.
The group says it makes people they represent seem like second-class citizens.
