Jacqueline Marie Baillie is a Scottish politician who has served as Deputy Leader of the Scottish Labour Party since 2020. She has been Member of the Scottish Parliament (MSP) for the Dumbarton constituency since 1999. She also served as acting Leader of the Scottish Labour Party in 2017 and again in 2021.
Born in British Hong Kong, Baillie was educated at St Anne's School, Windermere before studying at Cumbernauld College and the University of Strathclyde. After working in local government, she was elected at the 1999 Scottish Parliament election and served in the Scottish Executive as Minister for Social Justice under Henry McLeish. In December 2014, she was appointed as Scottish Labour Spokesperson for Finance, Constitution and Economy; later Economy, Jobs and Fair Work.
After Kezia Dugdale resigned as Leader of the Scottish Labour Party and acting leader Alex Rowley was suspended, Baillie served as acting leader until Richard Leonard was elected as Scottish Labour leader in 2017. She was sacked by Leonard as economy spokesperson in October 2018, who also replaced her in the role. After she was elected Deputy Leader of the Scottish Labour Party, Leonard reappointed Baillie to his Shadow Cabinet as Scottish Labour Spokesperson for Finance in April 2020. She again served as acting Scottish Labour leader for six weeks following Leonard's resignation in January 2021 and has been described by journalist Alex Massie as someone "who both loves to wind-up the SNP and is good at it".
