Demand for final models of the Land Rover Defender, due to end production in December, means that supplies could run short after the summer.

Land Rover has already increased daily production of the Defender at its Solihull plant from 100 to 120 units to meet demand after it revealed the final British-built Defenders would roll off the line in December 2015.

Land Rover officials have told Car magazine that the last Defenders could sell out by the time its special anniversary editions, badged Heritage, Autobiography and Adventure, arrive this summer.

The Britain-based 4x4 maker, owned by India's Tata Motors, is considering resuming Defender production abroad in low volumes for non-European markets, however it is understood it is too costly to ensure the vehicle continues to meet EU emissions and safety requirements.
