Liz Truss has said leaders must be bold, as she left Downing Street for the last time as British prime minister.

Speaking outside No.10 before meeting King Charles to resign, Truss quoted Roman philosopher Seneca.

It is not because things are difficult that we do not dare, but because we do not dare that they are difficult, she said.

Truss was prime minister for just 49 days, having taken over from Boris Johnson on Sept. 6.

Her premiership imploded after her mini-budget triggered chaos in the markets and tanked ratings for her Conservative Party.

But in her farewell speech she offered no apology and urged her successor to stick to her plan for lower taxes and focus on economic growth.

From my time as prime minister Im more convinced than ever that we need to be bold and confront the challenges we face, she said.
