Weil Gotshal & Manges tax partner David Irvine is set to join Kirkland & Ellis, as the firm continues to aggressively expand in London.

Irvine will join Kirkland as a partner later this year, two sources with knowledge of the matter told Legal Week. His move marks the second lateral boost for Kirkland’s expansive London base this year, after the firm last week sealed the hire of Freshfields Bruckhaus Deringer private equity partner Adrian Maguire.

Irvine joined Weil’s London office in 2011 from Clifford Chance, where he had been a senior associate. He was made partner at Weil in January 2016. He is the second Weil partner in London to leave in recent months, after banking head Mark Donald resigned from the firm late last year to join White & Case.

Kirkland overtook Latham & Watkins as the world’s largest law firm by revenue last year, taking in $3.2 billion, and has continued its sustained recruitment push in London. Last year, the firm launched a London intellectual property practice with the hire of Allen & Overy global IP head Nicola Dagg, who moved with a team of lawyers.

Kirkland is also preparing to launch its second continental European office in Paris after recruiting a pair of Linklaters partners. The firm is currently awaiting approval from the Paris Bar Association for the launch, with the partner duo—corporate lawyers Vincent Ponsonnaille and Laurent Victor-Michel—working out of London in the interim.
