His unexpected departure is believed to be the result of a personal clash with boss Kyle Whitehill Vodafones director of enterprise business unit.
Vodafone refused to be drawn in to the details of his departure but a spokesman revealed: "He is leaving to pursue other career opportunities."
Sources familiar with the company admitted Huggett did not attend a 400-strong internal Vodafone sales conference that he was due to participate in at the Newbury head office a couple of weeks ago.
Huggetts exit follows a number of high-profile executive departures at Vodafone over the last year. A rift in the company is reported to have grown between the so-called "Newbury Boys" a group of executives led by Sir Christopher Gent who oversaw the firms rapid expansion in the 1980s and 1990s and other senior management figures including chief executive Arun Sarin.
In March this year Gent further fuelled rumours of boardroom politics by stepping down from his position as life president further severing ties with the company.
The loss of other key figures includes the ousting of marketing director Peter Bamford in March and the imminent retirement of deputy chief executive Sir Julian Horn-Smith in July both thought to be part of a wider boardroom strategy by CEO Arun Sarin.
Other notable departures include former finance director Ken Hydon senior manager for business partnerships Jason Rigby and head of dealer sales Iain Graham.
This latest departure is likely to cause further concern for the company which has undergone significant changes over the past year including the sale of Vodafone Japan for £8.3 billion in March and the return of Bill Morrow from Japan to head the networks operations in Europe.
