Which 1839 political crisis centered on Queen Victoria's ladies of the bedchamber?

The 1839 political crisis over Queen Victoria’s ladies of the bedchamber was the Bedchamber Crisis.

It began when Whig prime minister Lord Melbourne planned to resign after his government narrowly lost support on a bill. Conservative leader Robert Peel was asked to form a ministry, but he wanted some of Victoria’s ladies-in-waiting replaced because many were connected to prominent Whig families. Victoria regarded the women as personal friends and resisted the request.

Peel consequently declined to become prime minister, and Melbourne remained in office. The episode exposed tensions between the monarch’s household preferences and the convention that royal attendants should not appear politically partisan. After the Conservatives won the 1841 election, Victoria accepted the replacement of several ladies, helped by Prince Albert’s advice. The crisis is sometimes described as the Bedchamber Plot, but “Bedchamber Crisis” is the standard quiz answer.
