Weil Gotshal & Manges boosted London profits by 40% during 2017, with the highest-paid member of the UK partnership taking home £1.2m, the US firm's accounts have revealed.

The accounts – the firm's first audited London limited liability partnership (LLP) filing since the office converted to an LLP in 2015 – also show that turnover for the UK arm of the business grew 18% during the year to £126.1m, up from £106.6m.

Operating profit rose 40% in the year from £40.6m to £56.9m, while pay for the LLP's top earner was up 27% from £955,000 in 2016 to £1.215m.

The average number of members in the City office remained static at 43 during the year, though the average staff numbers increased by three to 269.

Major mandates for Weil during 2017 included advising on Reynolds American's multibillion-dollar takeover by British American Tobacco. The firm acted for the Reynolds American transaction committee with a transatlantic team that included London managing partner Mike Francies and senior consultant Ian Hamilton.

Earlier this year, Weil reported that global revenues had reached $1.39bn for 2017, with PEP up 17.8% to $3.64m. According to executive partner Barry Wolf, Brexit uncertainty "cleared itself up in 2017", with London growth driven by the firm obtaining more market share.

In terms of partner movement, Weil's co-head of international dispute resolution Hannah Field-Lowes left the firm at the beginning of the year to join White & Case's City office, while in June, Baker McKenzie banking partner Paul Hibbert joined the firm to expand its real assets offering.

Key deals for Weil so far this year have included advising Mubadala Investment Company on the $2.3bn sale of its 60% stake in EMI Music Publishing to Sony, as well as advising Bain Capital on its £1.2bn bid for insurance company Esure.
