Nigel Farage is to launch a legal fight with NatWest over the debanking saga which culminated in the resignation of chief executive Dame Alison Rose.

The former Ukip leader said he is instructing lawyers to take action against NatWest Group, with the aim of turning it into a class action.

The banking giant has sought to draw a line under the row by scrapping about £7.6 million in potential payouts to its former boss after she left the company in July.

The scandal erupted when Mr Farage revealed in June that Coutts, which is owned by NatWest, was planning to close his account.
