BNP plans to axe 233 British jobs but will also be hiring 60 employees there -- bringing the net headcount down to 3,105 in 2016 from 3,278 in 2015, the source said without giving details on where the job cuts would come from.

A similar net number, 179 in all, will be hired in lower-cost Poland, increasing its staff there by about half to 507 employees.

Elsewhere in Europe, Italy would see a net decrease in headcount, while Spain, Portugal and Ireland would see some hiring, the source said.

Italy could see a net fall in headcount of 27 jobs in 2016, down from the 635 employees it had at the end of 2015.

The French bank has said it is targeting more than one billion euros of cost savings at its investment bank over the next three years, but outside of France, it has yet to put any numbers on resulting job losses around Europe.

It announced earlier in April a voluntary redundancy plan that calls for up to 675 job cuts at its corporate and institutional bank (CIB) in France, which employs 6,000 staff.

The CIB operations of BNP Paribas in Britain are headquartered in central London near Marylebone.

BNP Paribas declined to comment.
