Citigroup has promoted a former JPMorgan dealmaker it hired last year to co-head of UK investment banking, refreshing the leadership at a business that generates the biggest chunk of its European fee revenue.

Andrew Truscott has been named co-head of UK investment banking alongside Jan Skarbek, according to an internal memo sent by Michael Lavelle, Citi’s head of corporate and investment banking for the UK and Ireland, seen by Financial News.
