Barclays : Qatar's investments in Britain - Barclays, Sainsbury's, Harrods and IAG

The state-owned Qatar Airways has bought a $600 million stake in British Airways-owner IAG to increase its holding to 25.1%, advancing its strategy of building a global portfolio of international carriers.

Here are some of the wealthy Gulf state's other investments in Britain.

Barclays

The Qatar Investment Authority (QIA), the state's sovereign wealth fund, owns a 5.9% stake in Barclays, making it the British bank's second largest investor, according to Refinitiv data.

Sainsbury's

The QIA owns a 21.8% stake in Britain's second largest supermarket group, according to Refinitiv. The Qataris built up their stake during a failed bid attempt in 2007.

Harrods

The QIA bought the famous London department store Harrods from Egyptian-born businessman Mohamed al-Fayed in 2010 in a deal reported to be worth around 1.5 billion pounds.

Heathrow Airport

The QIA is part of a consortium that owns Britain's biggest airport, along with Ferrovial, China Investment Corp and others.

Canary Wharf

A QIA-led consortium purchased the owner of London's Canary Wharf business district in 2015 for $4 billion.

The Shard

The QIA also owns London's Shard skyscraper.
