British Prime Minister Boris Johnson’s younger brother, Jo, has resigned as a junior minister. In the speeech he stated that he would also step down as a lawmaker, citing a conflict between family loyalty and the national interest.

His surprise resignation comes days after the prime minister expelled 21 Conservative lawmakers from the party for failing to back his Brexit strategy, including Winston Churchill’s grandson and a former finance minister.

Since taking office in July, Boris Johnson has tried to corral the Conservative Party, which is deeply divided over Brexit, behind his strategy of leaving the European Union on Oct. 31, with or without a deal.

Jo Johnson, 47, had previously expressed backing for a second referendum on whether Britain should leave the EU, but accepted a job as a junior minister in the business and education departments when his brother became prime minister.
