After stints in
Pakistan and
Italy, interspersed with jobs in
Whitehall, Brummell received his first posting as
head of a diplomatic mission in 2002, as
Ambassador to Turkmenistan. In 2005, he made the relatively short move to head the
embassy in
Kazakhstan, a position that also includes being
non-resident ambassador to Kyrgyzstan. That same year his name was among a list of individuals claimed to be serving members of the
Secret Intelligence Service that appeared on the US website
Cryptome. In 2008 he invited the US ambassador,
Tatiana Gfoeller, to a meeting with the
Duke of York and British businessmen; her report to Washington,
leaked by WikiLeaks and reported by British and international media, mentioned indiscreet remarks by the Duke. In 2009 Brummell was transferred to
Bridgetown,
Barbados, where he served as
High Commissioner to
Barbados and the
Eastern Caribbean (
Antigua and Barbuda,
Dominica,
Grenada,
St Kitts and Nevis,
St Lucia, and
St Vincent and the Grenadines) until 2013, and was also UK representative to
CARICOM and the
OECS. Following this, Brummell served as
Ambassador to Romania from 2014 to 2018. He then held the position of Head of
Soft Power and External Affairs Department within the Communication Directorate of the
Foreign and Commonwealth Office. In July 2021, he succeeded Keith Shannon as
Ambassador to Latvia, == Honours ==
