On 10 October 2008 he and a number of followers founded the party Borgerligt Centrum. On 13 October 2008 he left the Social Liberal Party, which he had represented in parliament since the 2005 elections. On 6 January 2009 the incorporation of Borgerligt Centrum was announced. On 16 June 2009, he announced that he had joined Liberal Alliance and dissolved Borgerligt Centrum. The dissolution was strongly contested by those members of the board who did not follow him in leaving the party. He is notable for being the only Danish member of parliament to have been member of three different parties in less than a year. On 22 October 2019, Ammitzbøll-Bille left Liberal Alliance, citing political differences. On 7 November he founded the party Forward together with Christina Egelund, also former MP from Liberal Alliance.
Controversy
The remaining board members of the Borgerligt Centrum initiated legal proceedings against Simon Emil Ammitzbøll. They argued that he had violated a number of party by-laws. His attempt to dissolve the party had been exercised through coercion and without observing the articles of association. The party is still active with new leadership.
Personal life
Simon Emil Ammitzbøll-Bille is openly bisexual, and was married to another man, Henning Olsen until Olsen died in August 2016, after a long battle with cancer. In June 2017 he began a relationship with Kristine Bille, whom he married in November 2017. In October 2017, they announced that they are expecting their first child in the Spring of 2018. He was named the year's politician in 2006 by LGBT Danmark. LGBT rights have also been among Ammitzbøll's political affairs. In November 2008, he proposed a parliamentary resolution that would allow couples in a registered partnership to adopt children from other countries. Thanks to the support of the members of Liberal Alliance in the vote on 17 March 2009, the proposal was adopted, and same-sex couples were able to adopt jointly in Denmark from 2010.
Simon Emil Ammitzbøll-Bille traveled to Latvia in July 2006 to attend the second Baltic Pride. However, the parade had to be canceled shortly before, when the police of Riga were unable to guarantee the safety of the participants. The organizers decided to hold a conference on LGBT rights in Riga to replace the parade. However, they were attacked by angry demonstrators who surrounded a church in which Ammitzbøll-Bille and the other participants were part of that day's program. For several hours, the protesters shouted slogans and threw eggs, tomatoes and stools against the participants. After the event, Ammitzbøll-Bille stated about his experiences in the media, and in conjunction with other EU politicians, called for more rights for minorities in the former Soviet countries. On 3 June 2007 Simon Emil Ammitzbøll-Bille traveled again to Latvia, and this time it was possible to complete the parade with the protection of the Latvian authorities.
On 30 August 2011, and with 5.0% voter support, Simon Emil Ammitzbøll, told on air to Danish Radio, that a vote for the Liberal Alliance is a vote for free hashish.
