Canary Wharf-based Barclays was investigated more times than any other UK high street bank last year.
Officials from the Financial Conduct Authority made 186 visits to the bank’s UK headquarters in 2014 – twice as many as its Wharf neighbour HSBC.
The number is thought to be higher due to the differences in business model of each bank with Barclays boasting an additional investment banking arm as well as a presence in credit cards.
The figures were revealed by Bloomberg through a Freedom of Information request.
The Guardian reported there were rumours Barclays’ John McFarlane is on a cost-cutting drive that could lead to more job losses on top of the 19,000 announced last year.
