Belfast Dock strike was soon joined by carters and coal men, the latter settling their dispute after a month. With active support from the Independent Orange Order and its Grand Master, R. Lindsay Crawford, urging the "unity of all Irishmen", Larkin succeeded in uniting Protestant and Catholic workers and even persuaded the local Royal Irish Constabulary to strike at one point, but the strike ended by November without having achieved significant success. Tensions regarding leadership arose between Larkin and NUDL general secretary James Sexton. The latter's handling of negotiations and agreement to a disastrous settlement for the last of the strikers resulted in a lasting rift between Sexton and Larkin. Formation of Irish Transport and General Workers' Union and founding of the Irish Labour Party In 1908, Larkin moved south and organised workers in Dublin, Cork and Waterford, with considerable success. His involvement, against union instructions, in a dispute in Dublin resulted in his expulsion from the NUDL. The union later prosecuted him for diverting union funds to give strike pay to Cork workers engaged in an unofficial dispute. After trial and conviction for embezzlement in 1910, he was sentenced to prison for a year. This was widely regarded as unjust, and the Lord-Lieutenant, Lord Aberdeen, pardoned him after he had served three months in prison. Also in 1908, Arthur Griffith during the Dublin carter's strike described Larkin as an "Englishman importing foreign political disruption into this country and putting native industry at risk". After his expulsion from the NUDL, Larkin founded the Irish Transport and General Workers' Union (ITGWU) at the end of December 1908. The organisation exists today as the Services Industrial Professional & Technical Union (SIPTU). It quickly gained the affiliation of the NUDL branches in Dublin, Cork, Dundalk, Waterford and Sligo. The Derry and Drogheda NUDL branches stayed with the British union, and Belfast split along sectarian lines. Early in the new year, 1909, Larkin moved to Dublin, which became the main base of the ITGWU and the focus of all his future union activity in Ireland. In June 1911, Larkin established a newspaper, The Irish Worker and People's Advocate, as a pro-labour alternative to the capitalist-owned press. This organ was characterised by a campaigning approach and the denunciation of unfair employers and of Larkin's political enemies. Its columns also included pieces by intellectuals. The paper was produced until its suppression by the authorities in 1915.
