British Prime Minister Liz Truss is facing calls from her own Conservative Party to resign just six weeks after joining Downing Street.

Truss and her former finance minister, Kwasi Kwarteng, announced the tax package - the so-called mini-budget - on Sept. 23. The measures sent shockwaves through the market, from the pound falling to a pension panic, and rare public condemnation from the International Monetary Fund, CNBC reported.

Step by step, the plans have been adjusted, including canceling plans to repeal the corporate tax increase, cutting plans to repeal the income tax cap, and cutting the energy guarantee to subsidize energy bills for consumers and businesses.

The latest plans were announced Monday by Jeremy Hunt, just three days into his tenure as Treasury Secretary. He is the fourth person to take the job since July.

Truss fired Hunt's predecessor on Friday, and now lawmakers from across the political spectrum are urging her to follow him.

Elected members of Truss' own party are openly calling for her to leave, while it is believed that as many as 100 members have submitted letters of no confidence in the prime minister.

Angela Richardson, the MP for Guilford, said Truss can no longer remain as prime minister, speaking to the Times Radio, while Jamie Wallis, the Conservative MP for Bridgend, wrote a letter to the prime minister offering her resignation.

"I ask you to stand down as Prime Minister as I believe you no longer hold the confidence of the country or the parliamentary party,” Wallis’ letter said. “It is the right thing to do to ensure the stability, security and prosperity of the people to whom we owe everything.”
