His brother Nigel Feetham is currently a Government Minister for the GSLP having been elected for the first time in 2023 and holds both the portfolios that his father Michael (Trade and Industry) and Daniel (Justice) held.

He addressed the UN Fourth Committee on the decolonisation of Gibraltar in 2002 and 2003 advocating devolved integration with the United Kingdom.

In 2004, he introduced the then leader of the Conservative Party, Michael Howard, to the international press for the launch of the first European Elections in which Gibraltar was allowed to vote as part of the South West of England region and helped manage the campaign in Gibraltar for the Conservative Party.

Although the bill was defeated it eventually led to his own Government putting the matter before the Gibraltar Supreme Court, which agreed with Mr Feetham that the disparity was not constitutional.

In Opposition the GSD voted in favour of socially progressive measures such as civil partnerships and same sex marriage.

His attacker was on bail at the time on charges of attempted murder of a doctor at St Bernard's Hospital and stabbed Mr Feetham because he had been declined, by a judge, legal aid to retain an English QC to represent him rather than having local representation.

He is now the Managing Director of London Law Firm, Madison Legal and practices as a barrister from 3 Hare Court in Temple.

His brother, Nigel Feetham KC, was a Legal Partner (and Head of Financial Services) at Hassans and is now serving as an MP and Minister for Trade and Industry, Financial Services, Gaming and Justice (the latter that Daniel served as the inaugural minister from 2007 to 2011) with the GSLP-Liberal Government since the 2023 Gibraltar general election.
