The founder of one of Europe’s largest private equity firms has called for amicable negotiations over the UK’s “divorce” from the European Union, saying she is concerned that tough negotiations could create deeper division.

Dominique Senequier, the French founder and president of Ardian, says negotiations could go well if Brussels is prepared for some kind of compromise, but says she is concerned that politicians in Brussels and other European cities could take a line that drives the UK and the EU further apart. Ardian manages $60 billion.
