The UK government is to waive VAT on sales of the Military Wives' Christmas single.
According to the Daily Mail, the Treasury will give the money to charity in lieu of the tax taken from sales of Wherever You Are, which looks set to be Christmas number one.
Chancellor George Osborne and Defence Secretary Philip Hammond are said to have struck the deal after Conservative MP Oliver Colvile called for the tax to be waived.
A Treasury source told the newspaper: "George thinks this is an incredibly worthy cause and is sorting this out. We look forward to making an announcement shortly."
The Military Wives' song has become the fastest seller for six years and could hit the half-million mark by the end of the week, virtually guaranteeing a Christmas number one.
Proceeds from the single are being donated to the Royal British Legion and the Soldiers, Sailors, Airmen and Families Association.
