Robbie Mullen, Mr Renshaw’s accompanist of the anti-fascist group, has been in the organization for a long time.
Ms Cooper, 72, will now take up a position as Chair of the Mersey Care NHS Foundation Trust, describing the NHS as “one of my passions”.
During her time as an MP, she served on the House of Commons Selection Committee for Health and Social Care, where she scrutinized a number of health secretaries. She said her new job felt like “the right opportunity at the right time”.
Her unexpected departure from politics will lead to by-elections in the West Lancashire constituency, which was formed in 1983 and has been represented by Labor MPs since 1992.
Labor currently holds a majority of 8,336 votes after taking 52.1 percent of the vote in the 2019 general election – the fifth Ms Cooper won – while the Conservatives won 36.3 percent.
