Deutsche Bank, Goldman Sachs and JPMorgan have deployed their top equity advisory bankers to work on what will be the biggest public share sale in London this year — the £1bn listing of luxury carmaker Aston Martin.

The three banks have been named as joint global co-ordinators for the deal, which was announced on Wednesday. It follows months of speculation that the iconic brand, featured heavily in the James Bond film series, was set to go public.
