Antoinette Geraldine Mackeson-Sandbach (born 15 February 1969), known as Antoinette Sandbach, is a Conservative Party politician who was elected as the Member of Parliament for Eddisbury in Cheshire at the 2015 general election. The following day, 8 May 2015, she resigned as the Welsh Assembly Member for the North Wales region, having been elected as a North Wales regional Assembly Member at the May 2011 election.
Her paternal grandmother was Geraldine Mackeson-Sandbach, a prominent landowner in North Wales, whose estates included Hafodunos near Abergele and Bryngwyn Hall near Llanfyllin.  Her mother, Anne Marie Antoinette of the Dutch Van Lanschot family married Ian Mackeson-Sandbach in 1967.
In the 2007 Welsh Assembly election, Sandbach contested the Labour-held constituency of Delyn. She lost, but achieved a swing of 3.7% from Labour to Conservative and Labour narrowly held the seat by just 511 votes. Sandbach contested the Delyn parliamentary constituency in the 2010 general election, but lost again, though achieving a larger swing of 6.7% from Labour to Conservative. Following the death of Brynle Williams in 2011, she became a Conservative Regional Assembly Member for North Wales.
During her time in the Assembly she was appointed Shadow Rural Affairs Minister. In 2014, she was appointed Shadow Minister for the Environment. Sandbach also sat on the Assembly's Environment and Sustainability Committee.
In March 2015, Sandbach was selected as the Conservative Party candidate for the Conservative-held seat of Eddisbury in Cheshire, England. She held the safe Conservative seat with a majority of nearly 13,000, and promptly resigned from the Welsh Assembly, to be succeeded by Janet Haworth.
On entering the House she was elected to the Welsh Affairs Select Committee and the Energy and Climate Change Select Committee, which she sat on until it was disbanded in October 2016. In March 2017, she was elected on to the Business, Energy and Industrial Strategy Select Committee and has subsequently been re-elected to the Committee since the 2017 General Election. She has also been an elected executive member of the 1922 Committee of backbench Conservative MPs since 2015.
One of her main policy interests is improving services for those who suffer the loss of a baby. Following a debate in the House of Commons in November 2015, she helped set up the All-Party Parliamentary Group on Baby Loss, of which she was also appointed co-chair. Since its formation the group has made recommendations to the Department of Health and has been working closely with Ministers to improve policy in this area.
Sandbach has been a strong advocate for improving representation of women in the workforce. In some of her first appearances in the House she raised the issue of encouraging more girls to study Science, Technology, Engineering and Maths subjects in order for them to access those highly paid, highly skilled jobs and reduce the gap between men and women in the workplace.
In June 2018, Sandbach reported a 64-year-old constituent to the police for criticising her stance on Brexit in an email sent to the local Conservative Party office. Sandbach had been "copied-in" to the letter which she believed to be abusive and inappropriate. The story was widely reported by the UK print media, and gained additional prominence given Sandbach's long-standing demands that Parliament is given a free, meaningful vote on the final terms of the Brexit deal.
Sandbach-Mackeson's daughter Sacha was born in 2002 but she split from Sacha's father in 2003 and moved back to Hafodunos in 2005. She lost a five-day-old son, Sam, to SIDS in 2009 and married Matthew Sherratt, a sculptor, in 2012.
