Labour intends to deploy a white van to appeal to ethnic minority voters from around the country, BuzzFeed News has learned.
Initially, it was suggested that the party would use the vehicle to target working-class voters.
But BuzzFeed News understands that the van (which appears to be a minibus) will be part of a campaign, run by Labour MP Keith Vaz, to target ethnic minority voters across the country.
Vaz is chair of the party's Ethnic Minority Taskforce and he plans to use the minibus – dubbed "Labour's white van" – during the election campaign to urge people to vote for the party on 7 May.
The move follows the controversy over Labour's use of a pink minibus to attract female voters – and Ed Miliband's sacking of Emily Thornberry as shadow attorney general for apparently mocking white van drivers.
Greg Hands, the Conservative MP for Chelsea and Fulham, has already accused Labour of breaking the rules by leaving a campaign vehicle in the parliamentary car park.
He told BuzzFeed News: "You cannot use parliamentary facilities (in this case a parking space) for the promotion of a political party."
A spokesperson for the commissioner for parliamentary standards told BuzzFeed News that the office does not investigate political parties.
Instead, it would investigate individual MPs if it received a complaint and had evidence to begin an investigation.
She also said the commissioner "does have the power to investigate an MP when she has no complaint but she would need to have sufficient evidence".
