Jones Day has unveiled a bumper round of partnership promotions with 40 new partners added worldwide, including four in London.

The new partners in the City are Edwin Borrini in banking and finance, Paul Bromfield in business restructuring and reorganisation, Alistair Grant private equity and Julian Runnicles in M&A.

The new appointments bring the firm's total partner numbers in London up to 53 after a number of lateral hires over the year, including Peter Baldwin from Cadwalader Wickersham & Taft and Michael and Stephen Brown from Mayer Brown.

The promotions represent a slight drop on last year's round of 46 new partners, when London also saw four partners join the partnership rank.

This year, the bulk of the appointments come in the firm's US offices, with Cleveland, Washington, New York and Dallas the main beneficiaries.

Internationally, the firm's Paris, Brussels, Singapore and Taipei offices all gain one new partner apiece.
