The prime minister has been speaking outside Downing Street to announce her resignation.

Having spent just 45 days in office, Liz Truss announced she is stepping down with a Conservative Party leadership election to take place within the next week.

Here is her speech in full:

"I came into office at a time of great economic and international instability.

"Families and businesses were worried about how to pay their bills.

"Putin's illegal war in Ukraine threatens the security of our whole continent and our country has been held back for too long by low economic growth.

"I was elected by the Conservative Party with a mandate to change this.

"We delivered on energy bills and on cutting National Insurance.

"And we set out a vision for a low tax high growth economy that would take advantage of the freedoms of Brexit.

"I recognise, though, given the situation I cannot deliver the mandate on which I was elected by the Conservative Party.

"I have therefore spoken to His Majesty The King to notify him that I am resigning as leader of the Conservative Party.

"This morning, I met the chairman of the 1922 committee, Sir Graham Brady.

"We've agreed there will be a leadership election to be completed within the next week.

"This will ensure that we remain on a path to deliver our fiscal plans and maintain our country's economic stability and national security.

"I will remain as prime minister until a successor has been chosen.

"Thank you."
