On July 13, British Prime Minister David Cameron sent a letter to Israel’s outgoing ambassador to the United Kingdom, Daniel Taub, thanking him for his work in strengthening UK-Israel relations.

Taub, who is British-born and educated, assumed office in 2011. His replacement has not yet been announced.

“When you look back at your time serving in Britain, you should be proud of all that you have achieved,” wrote Cameron in the personally signed missive.

Cameron highlighted improved trade ties, which have doubled over the past decade, and joint cooperation in science, high-tech, and academia.

He also praised Taub for fostering the relationship between the two countries, and playing a “crucial role” in reaffirming Jerusalem and London’s shared diplomatic values.

“Relationships have also grown stronger and this was particularly evident when I visited Israel last year,” Cameron wrote.

“And thank you for the many kind things you have said about me!”

Cameron signed the letter informally, with just, “David.”
