Conservatives in Cornwall have chosen their candidate for a new constituency.
Sarah Newton said the NHS was her campaigning priority
An audience of 150 in Truro had three candidates to choose from for the new seat of Truro and Falmouth at a meeting on Tuesday night.
The prospective parliamentary candidate is Sarah Newton, 45, a director of a think-tank on ageing.
Voting was also open to constituents who were not members of the party. The county is getting a sixth MP because of rises in population.
Ms Newton, who was born in Cornwall but currently lives in London, said she would be moving back to the county next year to begin her campaigning work.
The married mother of three was educated in Cornwall, eventually becoming Head Girl at Falmouth School.
She was a director of the International Longevity Centre-UK, an independent think-tank, and is still a trustee of the charity.
As a Tory prospective candidate she said she will be focussing her campaign on one main subject.
"My priority is the NHS in Cornwall. I think it's at a crisis point," she said.
Health services in the county are currently facing a £31m projected deficit.
Because of a rise in population, the county is receiving a new MP in the next general election after recommendations by the Boundary Commission in 2003.
The commission said the county's current voter population of about 385,000 was entitled it to a sixth MP.
BBC South West Political Editor Chris Rogers said: "This could be the most winnable seat for the Tories in a county currently completely represented by Liberal Democrats."
