The formation of British Leyland in 1968 saw rivals Daimler and Bristol merge with Leyland, bringing the two competing rear-engined chassis (Daimler Fleetline and Bristol VR) together with the Atlantean. Though the Bristol brand was retained, Daimler was dropped and products were re-badged as Leylands. After the re-organisation, Leyland set out to develop a new rear-engined double-deck bus for the London market to replace the troublesome Fleetlines. This new vehicle, the Titan B15 spawned a simpler, non-integral offshoot, the Olympian, which debuted in 1980. Though the Olympian was meant as a direct replacement for the VR, Fleetline and Atlantean, the venerable AN68 continued in production alongside the Olympian until 1986. The last Atlantean for the domestic market rolled off the production line in 1984, the last of a batch for Merseyside PTE, while the export version remained in production for a further two years, with deliveries to the city operator in Baghdad, Iraq.
