But Jewish scholars now believe that the Tory leader could also be a direct descendant of the biblical Hebrew prophet, Moses.

It was always known that Cameron’s great-great-grandfather was the Jewish banker Emile Levita, who came to Britain as a German immigrant in the 1850s.

And now Dr Yaakov Wise at the University of Manchester has traced Cameron’s ancestry traced right back to a famous Jewish scholar of the 16th century.

David Cameron could be a direct descendant of Moses', a leading Jewish researcher believes

Emile Levita was a wealthy banker who became a director of the Chartered Bank of India, Australia and China, which had offices in Threadneedle Street in the City.

He took on all the trappings of an English gentleman - he hunted, owned a grouse moor in Wales, and started an educational tradition which has continued through to today's Tory leader, by sending his four sons to Eton.

His eldest son, Arthur, a stockbroker, married Steffie Cooper, a cousin of the Royal Family.

This union provides Cameron's link to the 'Mad' King George III, an ancestor he shares with the Queen  - making her his fifth cousin once removed.

Dr Wise has discovered that Emile Levita was himself a descendant of Elijah Levita, who lived from 1469-1549 and who pioneered Hebrew linguistic research during the Tudor period.

Elijah Levita also wrote what is thought to be the first ever Yiddish novel - called the Bove-bukh (The Book of Bove) written in 1507 and printed in 1541.

Levita is the Latin form of the name Levite, a Jew descended from the Tribe of Levi, the son of Jacob and one of the original twelve tribes of Israel.

He said: ‘It is possible that Cameron is a direct descendant of Moses or, at least, a cousin.

‘The leader of the Levites at the time of the exodus from Egypt was Moses, who was married with two sons named in the Bible.

'However, later descendants are unknown and many of today’s Levites, often carrying the surnames Levy, Levitan or Levita, could in fact be his descendants.'
