Bours' father is Dutch. She trained as an actress and singer at Mountview Academy of Theatre Arts. She was also a member of the D'Oyly Carte Opera Company from year 2000, and a resident at the Savoy Theatre in London. She went on to appear in Brookside, Peak Practice and Band of Gold and musicals and fronted 1940s-style big bands. However, Bours has said she "retired from showbusiness" in order to concentrate on politics.
Bours is a single mother to two children. She is currently in a relationship with UKIP leader Paul Nuttall.
Louise Bours used her surname "van de Bours" as late as August 2013 in her LinkedIn profile discussing her musical career, but later dropped the "van de" and appeared as "Louise Bours" on UKIP's MEP party list in 2013. The tussenvoegsel in her name was allegedly more of a stage name than a legal name, according to the Huffington Post.
Bours previously served as councillor on Congleton borough and town councils and was elected Mayor in 2006. In January 2015, Bours was disqualified as a councillor for Congleton town council after more than six months of non-attendance.
In 2012, she stood as UKIP's candidate in the Police and Crime Commissioner elections for Cheshire Constabulary, coming fifth with 7.86% of the vote.
As an MEP she served as UKIP health spokesperson, and came into opposition with former leader Nigel Farage on health issues; in particular Bours supports the principle of a free NHS, the English smoking ban and plain tobacco packaging, in opposition to Farage. However, Bours has opposed EU tax increases on electronic cigarettes, describing the proposals as "an act of sheer folly". Bours also opposes the Transatlantic Trade and Investment Partnership due to the impacts it would have on the NHS, saying in 2014 that: "TTIP is there for the benefit of one thing only — big business. I've got a message for Len McCluskey and Unite. UKIP will fight alongside you to ensure the NHS is excluded from this agreement."
Bours has famously appeared on Question Time discussing her role as health spokesperson.
Bours previously served as councillor for Congleton borough and town councils and was elected Mayor in 2006.
On 25 May 2014, Bours was elected as MEP for the North West England, replacing British National Party leader Nick Griffin. She has said that she wants to "shake off the BNP in blazers thing", for UKIP and it has been claimed that she has teamed up with UKIP MEP Paul Nuttall in the north-west, which has "a particular cause of anger" over a "cosy cartel" within the party according to former UKIP members.
In the 2015 general election, she stood for parliament for the Knowsley constituency. Bours came second, keeping her deposit.
