The tour will begin in early February and continue until 20 April, the deadline for voter registration for the 2015 General Election.
According to research conducted by the Electoral Commission, BME people are under-represented on the electoral register.
For example, 76% of Black people are registered to vote compared to 86% of White people.
OBV will work closely with the Electoral Commission, Bite the Ballot, Operation Disability Vote, the British Chinese Project, and local authorities to bring the “eXpress bus” to areas with high BME populations.
In London, these include Newham, Hounslow, Ealing, Lambeth and Tower Hamlets, among others.
OBV Director Simon Woolley said in a press release:
The 2015 General Election offers us a unique opportunity to make our democracy more inclusive and reflect our greater diversity.
Eligible voters visiting the bus will be able to register online using one of the 12 computer stations inside.
The bus will also act as a distribution point for leaflets encouraging people to participate in community activities and local and national politics.
Volunteers will also be on hand to answer questions.
OBV and its partners will announce the details of the tour on 5 February, National Voter Registration Day.
