David Cameron has admitted he botched the handling of the row over his financial affairs, telling Tory activists it had "not been a great week".
The Prime Minister confirmed he would publish his tax returns as he accepted the blame for the controversy over his connection to his late father's offshore business interests.
Speaking at the Conservative Party's spring forum in central London, he said: "It has not been a great week. I know that I should have handled this better, I could have handled this better.
"I know there are lessons to learn and I will learn them.
"Don't blame Number 10 Downing Street or nameless advisers, blame me."
