The Conservative Party in the United Kingdom lost the Wakefield and Tiverton and Honiton by-elections on Thursday, 23 June, and this is widely being perceived as a big blow to Prime Minister Boris Johnson's popularity.
The Labour Party won Wakefield, while the Liberal Democrats won Tiverton and Honiton.
Consequently, MP Oliver Dowden resigned as party chair of the Conservative Party.
"We cannot carry on with business as usual. Somebody must take responsibility and I have concluded that, in these circumstances, it would not be right for me to remain in office," he wrote in his letter to the prime minister.
Prime Minister Johnson is in Rwanda for the Commonwealth heads of state summit, before travelling to the G7 and NATO summits in Germany and Spain, respectively.
"This should be a wake-up call for all those Conservative MPs propping up Boris Johnson. They cannot afford to ignore this result," Liberal Democrats leader Sir Ed Davey was quoted as saying by The Guardian.
