Public affairs agency Insight has joined a five-strong international network of lobbying agencies set up by US member Blue Star Strategies.
The other agencies are Strategis Communications in Brussels, Cattaneo Zanetto & Co in Rome and Bay Global Strategies in Hanoi.
Blue Star Strategies is based in Washington and is led by CEO Karen Tramontano and COO Sally Painter.
Insight founder John Lehal said: "The work of Insight and BSS could not be more complementary. In Karen and Sally we have found the best in class and the Insight team looks forward to further collaboration with the Blue Star team to further assist our mutual clients as well as ones we have yet to work with."
