According to the official reports, Conservative Party leader David Cameron pledged to usher in a new era of government responsibility as British prime minister Tuesday, ending days of disarray.

The Times of London has reported that Cameron finally got the his chance to form a government Tuesday after five days of political drama following an election that saw the Labor Party lose its majority in Parliament and its leader, former Prime Minister Gordon Brown, step down from power.

U. S. President Barack Obama called Cameron to congratulate him and invite him to Washington.

Obama said in a statement, "As I told the prime minister, the United States has no closer friend and ally than the United Kingdom, and I reiterated my deep and personal commitment to the special relationship between our two countries, a bond that has endured for generations and across party lines, and that is essential to the security and prosperity of our two countries, and the world."

Buckingham Palace has said that Brown formally submitted his resignation to Queen Elizabeth II, who accepted. Brown had been involved in government for 13 years, 10 as chancellor and the past three as prime minister.

It was also reported that the genesis for the bang-bang-bang series of events Tuesday began Thursday when the Conservative Party won the most seats, but not a majority, resulting in a hung Parliament. Since then, negotiations for alliances have been under way between the Tories and Liberal Democrats, and between Liberal Democrats and Brown's Labor Party.

Cameron said after he met with the British monarch, "Her Majesty, the queen, has asked me to form a new government and I have accepted." He also paid tribute to Brown for his "long record of dedicated public service." (With Inputs from Agencies)
