Nationwide Building Society has received approval from the UK's competition regulator for its £2.9 billion ($3.75 billion) all-cash acquisition of Virgin Money UK. The deal, which faced scrutiny and was a significant topic at Nationwide's annual general meeting, is expected to bolster Nationwide's market position. The approval, which received support at the AGM, marks a major milestone for Nationwide's chief executive, who has been instrumental in pushing the controversial takeover.
