This Parliament was held before the office of Prime Minister had formally come into existence. However the Lord High Treasurer (or when that office was in commission the First Lord of the Treasury) was the most powerful and important minister of the Crown. The Lord High Treasurer at that time (in office in England and then Great Britain since 8 May 1702) was Sidney Godolphin, 1st Earl of Godolphin. Godolphin was a Tory, but the Ministry, as last reconstructed in February 1708, included both Tory and Whig members. The factions supporting the Ministry (the 'Court Party') were the Churchill Tories (followers of John Churchill, 1st Duke of Marlborough), Court Tory and Whig supporters of any Ministers the Queen cared to appoint, the Walpole-Townshend Whigs and Junto Whigs. They were opposed by the 'Country Party'. The main task of the Ministry was to support Marlborough's armies in continental Europe during the War of the Spanish Succession and Godolphin's financial expertise was essential to that task.
