Squire Patton Boggs has hired King & Wood Mallesons (KWM) energy partner Neil Upton alongside a team of four lawyers.

At KWM, Upton was the UK and Europe head and global co-head of the energy and infrastructure and project finance practice.

He is being joined at Squires by four energy lawyers, a paralegal and a business development specialist.

Upton's practice focuses on advising utilities, banks, governments and NGOs on structuring, development and financing of projects, M&A, trading issues, privatisation, market entry and regulatory matters in relation to the energy business.

During his career Upton has advised on the financing, acquisition and operation of several gas-fired power stations and also advised on a major gas supply pipeline in central and eastern Europe.

Robert Weekes, London office managing partner for Squires, said: "Neil fits so well with our teams here and globally. His appointment is a continuation of our strategic hiring in London, joining up practices and industry groups more closely and creating stronger links between international offices."

Upton said: "Squire Patton Boggs has the strategic, long-term commitment to global energy projects and the visibility, reputation and resources to deliver them successfully."

KWM has been hit by a number of senior departures in recent months. On 27 October, four partners resigned from the firm, causing it to suspend its recapitalisation programme, which had aimed to bring in £14m to strengthen the firm's balance sheet.

Two of those partners – former SJ Berwin managing partner Rob Day and corporate finance partner Andrew Wingfield – are set to join Proskauer Rose. It is not yet clear where UK investments funds head Michael Halford and private equity partner Jonathan Pittal are moving to.

News emerged today that the firm's newly elected European leaders – managing partner Tim Bednall and senior partner Michael Cziesla – are holding discussions with the management in China about a way forward for the European business, which could include the Chinese partnership providing some form of financial assistance to the legacy SJ Berwin business.
