Mr Brine has been MP for Winchester and Chandler’s Ford since 2010.
He will replace David Mowat MP, who has remained as pharmacy minister since losing his seat in the general election earlier this month.
In May 2015, Mr Brine was appointed as parliamentary private secretary to health secretary Jeremy Hunt. He also served as an assistant government whip from July 17, 2016 until last week (June 14).
According to Mr Brine’s website, he meets regularly with GPs and practice managers across the area to understand the issues they are facing. The MP is also described as a “passionate defender” of primary care as the gateway to the NHS.
