Private equity firm Duke Street has promoted Charlie Troup to managing partner.

Troup (pictured) specialises in investments in the healthcare, financial services, business services, and consumer sectors.

Troup joined Duke Street as a partner in 2006 from investment company Permira. Joining Permira in 1995, Troup became a partner at the firm in 2001.

Before Permira, he spent two years with HSBC Private Equity (now Montagu Private Equity) on secondment from Deloitte and Touche Corporate Finance. There, he was a senior manager specialising in raising private equity for management buy-in and management buyout transactions.

Troup has a mechanical engineering degree from London's Imperial College and is a qualified chartered accountant.

Duke Street also promoted Stuart McMinnies to managing partner. McMinnies joined Duke Street in February this year from private equity house 3i.

Miles Cresswell-Turner, another partner, has become specialist adviser at the firm.

This is while investment directors Jason Lawford and Ben Long, along with fundraising director James Almond, have been promoted to partners at the firm.

Both McMinnies and Troup join Peter Taylor, Duke Street's longstanding managing partner.

Duke Street own complex care provider Voyage Care, which it reacquired from Hg Capital in a £375 million deal last year.

The private equity house did the deal as part of a consortium with French partner Tikehau and Swiss investment firm Partners Group.

This summer, Duke Street sold Irish home care provider Baywater Healthcare to Air Liquide for an undisclosed sum.
