The UK Independence Party has donated the money it received from the controversial ‘Ukip Calypso’ song to an unnamed charity after the British Red Cross turned it down.

Money raised by former Radio 1 DJ Mike Read’s song had initially been offered to the British Red Cross' Ebola fund but that charity had rejected the donation, saying: “As a neutral organisation, we cannot benefit from something which overtly supports one political party. In addition, the Red Cross has a proud history of helping refugees and asylum seekers who are negatively referred to in the lyrics.”

Dan Corry, chief executive of the think tank NPC, criticised the party for not naming the charity that had taken the money.

“The idea that any charity can accept a donation raised like this but remain anonymous is very troubling,” he said. “The money was originally raised on the promise that it would fight the Ebola outbreak—but now no one will confirm whether this promise to donors has been honoured or not.

“This is against the principles of transparency. Political parties have every right to give cash to charities, but it can’t take place behind some veil of secrecy.”

Last October the radio DJ and presenter, Mike Read, released a cover version of Calypso as a digital download to raise money for Ukip and victims of Ebola.

Critics were quick to brand the track racist and offensive as it included the lyrics "Our leaders committed a cardinal sin/Open the borders let them all come in/Illegal immigrants in every town/Stand up and be counted Blair and Brown" and was sung in a mock Carribean accent.
