Advent International is due on Monday to cement its position as the world’s biggest mid-market private equity firm with the news it has raised a new €6.6bn ($10.3bn) fund.

The amount suggests investors are looking to put more money with private equity firms that are more likely to do deals soon. The “mega buy-out” firms are hampered by the crisis in debt markets, while mid-sized buy-outs are less reliant on plentiful supplies of cheap credit.
