Qatar will invest £5 billion in Britain over the next five years in a boost for the post-Brexit economy, Prime Minister Sheikh Abdullah bin Nasser bin Khalifa al-Thani announced Monday.

"Over the next three to five years Qatar will invest £5 billion ($6.23 billion, 5.8 billion euros) in the UK economy through various investment funds and relevant parties in Qatar -- which will constitute another addition to its already successful investments in the UK," he said at the Qatar-UK Business and Investment Forum in London.
