"Just spoke to the remarkable Bob Geldof," tweeted the politician. "Told him we'll waive VAT on #BandAid30 so every penny goes to fight Ebola."
In a break from previous Band Aid records, some of the famous song's lyrics have been altered to link it to the Ebola crisis in Africa.
A new line reads: "Where a kiss of love can kill you - And there's death at every tear", while another adds: "Well tonight we're reaching out, and touching you."
"No peace and joy this Christmas in West Africa - the only hope they'll have is being alive," the song continues. "Where to comfort is to fear - Where to touch is to be scared. How can they know it's Christmas time at all."
Band Aid 30 will be released on Monday 17 Novemeber.
