2017 
 In 2017 the contaminated blood scandal, in which many haemophiliacs died from infected Factor medicine, hit the headlines and Parliament with allegations of an "industrial scale" criminal cover-up. MP Ken Clarke retracted remarks from his autobiography relating to the scandal and a public inquiry is now underway.

Salmond claimed that senior figures in Sturgeon's government and the ruling Scottish National Party (SNP) conspired against him for political reasons.

Further allegations of harassment emerged against Pincher, along with claims that Prime Minister Boris Johnson had already been informed of his behaviour.  The incremental effect of this and other recent controversies led to the resignation of 59 Conservative politicians, most notably Rishi Sunak as Chancellor and Sajid Javid as Health Secretary. This in turn, led to Boris Johnson committing to resign as leader of the Conservative Party, and thus as prime minister, when his replacement as leader had been chosen by his party.
