A former Brighton councillor has been chosen to stand in Lewes for the Conservatives at the next general election.
Miss Caulfield overturned a four-figure majority to win a safe Labour seat in Moulsecoomb and Bevendean in 2007 although Labour took it back at the next local elections in 2011.
During her four years as a councillor, she became the council’s cabinet member for housing. She is a member of the board of Brighton Housing Trust (BHT).
Ms Caulfield works full-time as a breast cancer research sister at the Royal Marsden Hospital in London. She is also a part-time shepherd.
She is the Conservative Party’s south east region deputy chairman and a shareholder in Lewes Football Club.
At the 2010 general election she also stood in safe Labour territory – Caerphilly – where she came second.
Mr Baker, 56, a Home Office minister in the coalition government, will be defending a majority of 7,647 at the next election which is expected to be held in May 2015.
