Martin is gearing-up for a possible £5billion stock market flotation after it revealed record annual sales.

Revenues leapt 48% to £876million as it sold nearly 6,000 cars – the highest for nine years – and reversed a £163m loss into an £87m profit.

The move comes as the company has just begun deliveries of a limited edition DB4 GT Continuation costing £1.5m each. And it has said listing on the stock market is an option.
