Prime Minister's Questions is "the single most nerve-wracking thing you'll ever do", former Tory leader Iain Duncan Smith has warned Theresa May.
The new prime minister faces her first PMQs today and Mr Duncan Smith described the experience as being "just impossible".
But he said the new leader will have an easier ride because her opposition will not give her a tough time.
The MP for Chingford and Woodford Green said Mrs May is "blessed" to have Jeremy Corbyn standing opposite her, because he "never follows up a weak answer".
Mr Duncan Smith, who faced Tony Blair at PMQs from 2001 to 2003, told Good Morning Britain: "It's the single most nerve-wracking thing you'll ever do in your life, very few people have actually done it."
Britain is to relinquish its upcoming six-month presidency of the European Council in 2017, Downing Street has said.
Prime Minister Theresa May told council president Donald Tusk of the decision on Tuesday.
The presidency rotates between the 28 EU member states on a six-monthly basis, giving each the opportunity to shape the agenda.
The UK was due to hold the seat in the second half of 2017, but Mrs May has decided Britain should skip its turn in the light of last month's referendum vote for Brexit.

Prime Minister Theresa May said she wasn't going to gamble on Britain's safety, as she opened a commons debate on whether to renew Britain's nuclear deterrent.
The Government is committed to replacing the country's ageing fleet of submarines, a motion which Jeremy Corbyn has been vocally against.
Divisions in the Labour party were once again laid bare, as many of Mr Corbyn's own MPs stood up to disagree with him.
Our Political Correspondent Carl Dinnen reports:
MPs have voted in favour of renewing the UK's Trident nuclear deterrent by 472 votes to 117 - a majority of 355.
The result is a strong vote of confidence in the weapons system, renewal of which is predicted to cost £31 billion, with a £10 billion contingency fund also set aside.
The vote follows a near six-hour debate in the Commons in which Labour leader Jeremy Corbyn opposed the motion, earning him strong criticism from many in his own party.
Theresa May, who made her first despatch box appearance as prime minister, spoke in favour of the motion, warning it would be a "reckless gamble" for the UK to rely on other nations for its nuclear deterrent.
Labour MPs reacted angrily after Jeremy Corbyn referred to the party's policy on the UK's nuclear deterrent in the past tense.Read the full story ›
