Jones Day has billed Chrysler more than $18.5m (£12.3m) during the past five months, reports The Am Law Daily.

In late November the embattled car manufacturer paid Jones Day $1m (£660,000) to establish a retainer, and according to the US firm’s application to be Chrysler’s lead counsel, around $5.8m (£3.8m) remains in the retainer, meaning the firm has drawn down more than $13m (£8.6m) so far.
