After the establishment of civil partnerships, several individuals and groups advocated extension to opposite-sex couples. A campaign group known as Equal Civil Partnerships was organised, specifically to call upon the government to extend civil partnerships to all couples. A London couple, Rebecca Steinfeld and Charles Keidan, sued for recognition of their relationship as a civil partnership, but were unsuccessful in the High Court on 29 January 2016 and again in the Court of Appeal on 21 February 2017. The "Civil Partnership Act 2004 (Amendment) Bill 2016-17", a private member's bill, was filed by Tim Loughton on 21 July 2016 to amend the Civil Partnership Act 2004 and extend civil partnerships to opposite-sex couples, but after second reading debate took place on 13 January 2017, further debate was postponed and eventually cancelled due to the calling of a general election in June 2017.
