All three of the main parties promised to take action on Lords reform in the 2010 general election, and following it the Coalition Agreement included a promise to "establish a committee to bring forward proposals for a wholly or mainly elected upper chamber on the basis of proportional representation". Deputy Prime Minister Nick Clegg introduced the House of Lords Reform Bill 2012 on 27 June 2012 which built on proposals published on 17 May 2011. However, this Bill was abandoned by the Government on 6 August 2012 following opposition from within the Conservative Party. A successful attempt to pursue minor reform of the House was made on 14 May 2014 when the House of Lords Reform Act 2014 gained Royal Assent.
