Qatar Airways Group has revealed it now owns more than a quarter of shares in British Airways owner International Airlines Group (IAG) after upping its stake.

Qatar Airways increased its holding in IAG to 25.1% from 21.4% as it cheered its "highly successful" investment in the airlines group, which also owns carriers including Ireland's Aer Lingus and Iberia in Spain.

It spent £465 million on the extra shares, based on IAG's closing price on Tuesday.

Akbar Al Baker, chief executive of Qatar Airways, said: "Our investment to date has been highly successful and the announced increase in our shareholding is evidence of our continued support of IAG and its strategy.

"Qatar Airways continues to consider opportunities to invest in airlines and support management teams that share our vision to enhance travel opportunities for airline passengers across the globe."

Qatar Airways first invested in IAG in 2015, when it bought a 10% stake.

The Gulf state company also has holdings in China Southern and Cathay Pacific airlines and announced earlier this month it had agreed to buy a 49% stake in Africa's RwandAir, while it is in talks to double its stake in Chile's LATAM Airlines Group to 20%.

"Mark Lewis has indicated to the board that he wishes to step down as chief executive and pursue his career in a new direction," the company said in a statement released to shareholders on Wednesday.

It has already kicked off the formal search process to find a replacement for Mr Lewis.

"The board is grateful for Mark's contribution to the group," the company said.

The statement continued: "In the three years since Mark became CEO, the group has helped households save over £6 billion, returned £250 million to shareholders, launched new personalised customer experiences, and developed new capabilities in business-to-business services and the digitisation of mortgage comparison under the reinvent growth strategy."

Mr Lewis announced his departure a day before he is set to present the company's preliminary results for the last financial year alongside finance chief Scilla Grimble.

The company said the figures will show that it "met market expectations for 2019".

No date has yet been set for Mr Lewis's departure, but the board said he is committed to ensuring the transition is smooth.

High street lender Metro Bank has appointed interim chief Dan Frumkin as its permanent chief executive as the group looks to recover after a tough year.

The 55-year-old has been interim chief executive since January 1 after former boss Craig Donaldson stepped down in December amid falling profits and the fallout from an accounting blunder.

Mr Frumkin was previously Metro Bank's chief transformation officer, having joined the group last September.

Before that, he spent eight years at The Bank of NT Butterfield & Son Limited - a community bank based in Bermuda - most recently as global chief operating officer.

He also previously held roles at Royal Bank of Scotland and Northern Rock.

Metro Bank chairman Sir Michael Snyder said: "The combination of three decades of experience across retail banking and the positive impact he has made since joining Metro Bank last year mean we have identified an impressive CEO to take Metro Bank into its second decade."

Mr Frumkin said: "This is a business with robust foundations and real potential to shake up British banking.

"I am excited about the opportunity and look forward to updating the market on our plans on February 26."

He will be paid an annual salary of £740,000, with potential bonuses worth up to £1.48 million on top.

His appointment comes ahead of the group's full-year results on February 26, which are expected to show the impact of a difficult year.
