Liberal Democrats and the Conservative and Unionist Party, all of which organise and stand in elections across Great Britain and hold representation in both the Scottish and UK Parliaments. These three parties have philosophical differences about what Scotland's status should be, particularly in their support of devolution (historically Home Rule) or federalism. Other groups The Grand Orange Lodge of Scotland also supports the continuation of the Union. In March 2007, the Lodge organised a march of 12,000 of its members through Edinburgh's Royal Mile to celebrate the 300th anniversary of the Union. The high turnout was believed to be in part due to opposition to Scottish independence. The Orange Order used the opportunity to speak out against the possibility of nationalists increasing their share of the vote in the 2007 Scottish Parliament election. In the run up to the 2014 Scottish independence referendum, the Orange Order held a Unionist march and rally in Edinburgh which involved 15,000 Orangemen, loyalist bands and no voters from across Scotland and the UK. During the 2014 referendum campaign, a pro-Union rally by the "Let's Stay Together Campaign" was held in London's Trafalgar Square, where 5,000 people gathered to urge Scotland to vote "No" to independence. Similar events were held in other cities across the rest of the United Kingdom, including in Manchester, Belfast and Cardiff. Ties to Unionism in Northern Ireland There is some degree of social and political co-operation between some Scottish unionists and Northern Irish unionists, due to their similar aims of maintaining the unity with the United Kingdom. For example, the Orange Order parades in Orange walks in Scotland and Northern Ireland. This is largely concentrated in the Central Belt and west of Scotland. A unionist rally was held in Belfast in response to the referendum on Scottish independence. Northern Irish unionists gathered to urge Scottish voters to remain within the United Kingdom.
