Australia's former prime minister Tony Abbott says he is pleased to be officially appointed as Britain's trade adviser as the country seeks to negotiate new post-Brexit deals.
"The world especially needs arrangements that boost prosperity at a time like this and I am only too keen to help," he said in a statement.
The 62-year-old is among several senior figures from a range of backgrounds who will advise the government on trade and investment but "will have no direct role in striking trade deals", the UK government said in a statement.
Britain is forging its own international trade policy for the first time in decades following its split with the European Union, and is currently negotiating deals with Brussels, the United States, Japan, Australia and New Zealand.
"At a time of increased protectionism and global insecurity, it's vital that the UK is a strong voice for open markets and that we play a meaningful role in reshaping global trading rules alongside like-minded countries," International Trade Secretary Liz Truss said.
"The new board will help us do that, bringing together a diverse group of people who share Britain's belief in free enterprise, democracy, and high standards and rules-based trade."
But leaked news of Mr Abbott's appointment sparked criticism from the opposition Labour party and campaign groups due to his past use of sexist language, scepticism of man-made climate change, and opposition to same-sex marriage.
"Tony Abbott and his views should have no place representing Britain," said Emily Thornberry, trade spokeswoman for the main opposition Labour party.
Prime Minister Boris Johnson said earlier that "I don't agree with everyone who serves the government in an unpaid capacity", but said he should not have to.
"What I would say about Tony Abbott is this is a guy who was elected by the people of the great liberal democratic nation of Australia," he said.

"It's an amazing country, it's a freedom-loving country, it's a liberal country. There you go, I think that speaks for itself."
Mr Abbott's predecessor as prime minister, Julia Gillard, was pushed to comment on his impending appointment in an interview with Sky News television on Friday.
She famously accused him of sexism and misogyny in a 15-minute speech in parliament in 2012. But she said it was "a decision for the UK".
"I said everything I needed to say back in October 2012... I doubt I would be able to put it better in my life," she said.
