Janey Godley, a Scottish comedian, actor and writer whose hard-hitting, candid wit established her as a comedy star and who became known for her parody voice-overs of elected leaders during the coronavirus pandemic, died on Saturday in Glasgow. She was 63.

She died of ovarian cancer at the Prince and Princess of Wales Hospice, according to her manager, Chris Davis.

Ms. Godley, with her signature candor, announced in September that she had exhausted her treatment options and had entered palliative care. She is survived by her husband, Sean Storrie, and a daughter, Ashley Storrie.

Ms. Godley gained a following during the coronavirus pandemic for sharing parodies that reimagined what officials were saying — or perhaps secretly thinking — during their public addresses. One favored subject was Nicola Sturgeon, Scotland’s leader at the time.

Ms. Sturgeon seemed to appreciate the humor, calling Ms. Godley her “alter ego.” Ms. Godley’s videos, some observers said, led her to become a “distinctive” voice during the pandemic that helped spread public health messages.

Other world leaders were not exempt from being targets. Ms. Godley’s voice-overs also included former Prime Ministers Boris Johnson and Theresa May of Britain, former President Donald Trump of the United States and Queen Elizabeth II of England.
