And the biggest fallers?
Virgin Money UK PLC (ASX: VUK)
The worst performer on the ASX 300 today is the Virgin Money UK share price, down 6.52% to $3.655.

According to the publication, United States-based Global Payments has formed a strategic alliance with Virgin Money UK. The partnership agreement aims to redefine the future of digital commerce with the launch of a new connected payment offering.
Despite the positive announcement, Virgin Money UK shares are continuing to be under pressure from investors, falling four consecutive days.
