NatWest is facing a High Court lawsuit for £250 million from Rockfire Capital, a company central to the Thurrock Council investment scandal. Rockfire Capital, formerly known as Rockfire Investment Finance, accuses NatWest of aiding alleged breaches of fiduciary duty by Sean Clark, Thurrock Council's former finance director. The lawsuit comes amidst ongoing legal actions by Thurrock Council itself, which is seeking to recover hundreds of millions of pounds lost through investments in renewable energy, largely facilitated by Liam Kavanagh and Rockfire.

Rockfire Capital's claim asserts that NatWest provided banking facilities and services to Rockfire Investment Finance and its subsidiary, Toucan Energy Holdings 1. It alleges that NatWest had knowledge, or ought to have had knowledge, of a conflict of interest in Clark's dealings with Rockfire. The lawsuit argues that NatWest's actions, including allowing Clark to operate accounts and transfer funds, contributed to the financial losses suffered by Thurrock Council and subsequently by Rockfire due to the collapse of these investments.

Thurrock Council effectively declared bankruptcy in 2022 after accumulating a debt of approximately £1.5 billion, much of it from speculative investments in solar farms arranged through Liam Kavanagh and Rockfire. Kavanagh has admitted to personally benefiting from a "substantial part" of these funds, spending millions on luxury items such as a £13.7 million yacht and a £9.1 million private jet. The council's debt has since been reduced to around £677 million. The various legal actions, including this new suit against NatWest, highlight the complex and interconnected nature of the scandal, with multiple parties now seeking to assign blame and recover losses.

The case underscores the broader issues of governance and due diligence in local authority investments, particularly concerning the extent to which financial institutions bear responsibility when public funds are mismanaged. The outcome of this lawsuit could set precedents for how banks are expected to monitor transactions involving public sector bodies and their appointed financial officers. Both NatWest and Rockfire Capital are preparing their legal arguments, with the full implications of the case yet to unfold.
