Metro Bank has a limited future, claims co-founder

"I would not like to be the chairman or the chief executive of Metro Bank today," said Mr Thomson, who after leaving Metro Bank in 2012 set up Atom Bank - an internet-only company that has no physical branches.

When the financing deal was announced late on Sunday, Metro Bank's current chief executive, Daniel Frumkin, said the deal marked "a new chapter" for the bank.

The bank is still planning to open 11 new stores in the north of England by 2025. However, analysts have said that branches are expensive and run counter to the trend of consumers switching to online banking.

It positioned itself as a so-called "challenger" bank to the big High Street names, with its promise of keeping branches open seven days a week. It currently has 76 branches, and also offers online and mobile banking services to consumers and businesses.

However, the lender faced a major challenge in 2019 following an accounting scandal, which led to some top executives leaving the company.

More recently, it had asked regulators to reduce the amount of money it had to hold in reserve to cover its mortgage lending. That would have freed up cash so it could go out and continue to grow its business.

But regulators turned down the request last month, knocking about 20% off Metro's share price.

Last week, the bank's share price slumped again following reports that it was seeking to raise money from investors. This led to several days of speculation about the bank's future until the fund-raising deal was announced late on Sunday evening.

"It's terrible to see what's happened to such a great bank, and more importantly, a bank that had such a great customer franchise," Mr Thomson said.

"It's been a huge success. from a customer perspective, financially, less so."

He said the bank had "never really recovered" from the accounting scandal in 2019.

When it announced the financing package, Metro Bank said it had seen a "recent increase in deposit outflow rates" from current accounts ahead of the deal.

However, throughout the speculation of the past few days, the bank has insisted that its finances remain strong and it continues to meet all regulatory requirements.

Under the terms of the financing deal, Colombian billionaire Jaime Gilinski Bacal will become Metro Bank's controlling shareholder with a 53% stake.

His firm, Spaldy Investments, will sink 拢102m into the bank.

Metro Bank's shares rebounded on Monday following news of the deal and continued to rise on Tuesday to trade at about 55p.

However, the share price has more than halved since the start of the year, and is well below the peak of 拢40.19 it reached in 2018.

Who is Jaime Gilinski Bacal?

In Colombia Jaime Gilinski is a household name. Locally, he's never too far away from the headlines, with his business empire growing from strength to strength it would seem, both at home and abroad.

The 65-year-old businessman was born in Cali, a descendant of Lithuanian immigrants. His family set up several mid-sized businesses and built a reputation for themselves within Colombia's Jewish community and across the city.

But Mr Gilinski had bigger ambitions. After a US education he had a stint on Wall Street, and led his family group into purchasing several banks in Colombia and abroad.

A smart operator, Mr Gilinski has aligned himself with Colombia's political and business elite over the years.

Most recently, in 2022 Gustavo Petro was elected as the country's first left-wing president, promising action against what he called the country's "oligarchy".

However, local media reported that Mr Gilinski had quietly been building relations with Mr Petro, helping to avoid becoming a target.
