As Hogan & Hartson and Lovells hurtle toward the biggest trans-Atlantic merger in years, the firms’ top leaders have hit the road in advance of a partnership vote on the deal in mid-December.

News of the Hogan-Lovells engagement broke on Oct. 8, and plans call for a merged firm to make it to the altar on May 1 — a scant six months from now. Both firms have declined to comment publicly on details that have leaked out about the proposed structure for the merged firm.
