Britain was waking up Friday to the propsect of a hung parliament after one of the most fiercely-fought general elections in decades left no party with a clear enough majority to form an effective government. As results from across the country rolled in, the Conservative Party of David Cameron looked to have gained more parliamentary seats than incumbent Gordon Brown's Labour Party. The Liberal Democrats failed to live up to an exuberant campaign spurred by the stellar performance of their leader Nick Clegg in the country's first ever televised prime ministerial debates, but their party could still hold the key to power. Brown -- who as incumbent will be given the first opportunity to form a coalition government -- gave no indication early Friday that he would step down. The "outcome is not yet known but my duty ... is to play my part in Britain having a strong, stable and principled government," he said as he won re-election to his seat in Scotland. "I will not let you down." "I am very determined and have been through quite a lot in my political career and in my personal life, and I am used to difficulties." He arrived at his Downing Street residence in London at 7 a.m. (2 a.m. ET) and walked quickly inside, saying nothing in response to reporters' questions about whether he would resign.
