Unite, an influential union has been linked to The Venezuelan Solidarity Campaign.
The Venezuelan group publicly supports the recent elections in the country, despite the international community blasting them for being rigged.
A spokesperson for The Venezuelan Solidarity Campaign warned that “Britain and other governments should be respecting the democratic decisions of the Venezuelan people.”

The pro-Chavez open letter, from 2007, was co-signed by other high-profile Labour politicians, including Tony Benn and then-London mayor Ken Livingstone.
Green Party co-leader Caroline Lucas – who was then an MEP – also added her name to the gushing letter, published in the Guardian.
The signatories wrote: “We believe that the lives of millions of Venezuelans have been transformed by the progressive social and democratic policies of Hugo Chavez’s government.
