Parliament reconvened in April 1690 in an atmosphere of high tension due to the Jacobite war in Ireland, fears of an Irish invasion of Scotland and continuing unrest in the Highlands. An alleged Jacobite conspiracy called the Montgomery Plot was uncovered, involving Montgomery, the Marquess of Annandale and Lord Ross. In the resulting panic, Melville agreed to abolish the Committee of the Articles, although it is still unclear how serious the plot actually was. Its principal objective achieved, the Club disintegrated, and on 7 June Parliament approved an Act ending Episcopacy and a grant of taxes.
