Danish politicians are planning to limit the number of the Queen's grandchildren who will receive an annual salary from the state.

Queen Margrethe II has eight grandchildren with politicians stating that "simple mathematics" would require them to look again who is eligible for funding.

There has been cross-party that Crown Prince Frederik's son, Prince Christian, will continue to receive the state-funded salary as he is second-in-line to the throne.

Prince Christian's three younger siblings and the four children of the Queen's second son, Prince Joachim, are thought to lose their eligibility.

A MP for the ruling Venstre party, Jan E. Jørgensen, told Politiken: "Simple mathematics dictate that there needs to be some sort of limit.

"Otherwise within a few generations there will be several hundred princes and princesses who need an annual salary."

Critics in the Folketing (Danish Parliament) have called for the heir to the throne, Crown Prince Frederik, to share his own salary with his children instead of the government paying them their own stipend.

Tax spokesman for the Liberal Alliance party, Ole Birk Olesen said: "I'd rather go back to the old system, so that only the Crown Prince Frederik's first-born, who are entitled to annuities.

"Government finances should only have the task of supporting one of his children, who will inherit the throne after him."

The Royal Family's spokespeople have declined to comment on which of the grandchildren they want to receive annuities.
