 Santander is close to naming William Vereker, the former business envoy of former prime minister Theresa May, as its new UK chairman, tasked with overseeing one of the countrys largest high street banks amid the coronavirus pandemic. Mr Vereker, who joined JPMorgan only five months ago, will replace Shriti Vadera when she steps down later this year to become chair of British insurer Prudential, according to two people familiar with the appointment. Santander and JPMorgan declined to comment.
