CYBG – the holding company that owns Clydesdale Bank, Yorkshire Bank and the app-based bank B – has formally completed its £1.7 billion takeover of Virgin Money.

CYBG chief executive David Duffy, said: "Today marks an historic milestone for CYBG and Virgin Money, creating the first true national competitor to the status quo in UK banking with a clear ambition to provide customers with the best service in the UK.

"Bringing the two banks together creates the UK's sixth largest bank combining strong product, service and technology capabilities alongside an iconic brand with well-known consumer champion credentials.

"We are focused on delivering an excellent customer experience as we bring the two businesses together. This will be achieved through a clear, low-complexity, phased integration and re-branding plan over the next three years.

"This is a unique combination that will enable us to compete with the large incumbent banks."
