Sarah Southern (born 1980, Newcastle-upon-Tyne, England) is a British businesswoman and former Conservative Party official and aide to Prime Minister David Cameron. In 2012, she became embroiled in the so-called "Cash for Access" controversy after undercover journalists from The Sunday Times filmed the Conservative co-treasurer Peter Cruddas apparently offering access to the Prime Minister and his Chancellor George Osborne for £250,000. Southern is alleged to have introduced the journalists to Cruddas, while boasting to friends she had made "a tidy sum" by introducing people to the Prime Minister.
