Although the Tories were dismissed from office for half a century, for most of this period (at first under the leadership of Sir William Wyndham), the Tories retained party cohesion, with occasional hopes of regaining office, particularly at the accession of George II (1727) and the downfall of the ministry of Sir Robert Walpole in 1742. They acted as a united, though unavailing, opposition to Whig corruption and scandals. At times they cooperated with the "Opposition Whigs", Whigs who were in opposition to the Whig government; however, the ideological gap between the Tories and the Opposition Whigs prevented them from coalescing as a single party. They finally regained power with the accession of George III in 1760 under Lord Bute.
