The husband of a woman murdered on her honeymoon has been arrested in the UK at the request of the South African authorities, police said.
Anni Dewani, 28, from Sweden, was shot after being kidnapped while in a taxi with her husband Shrien last month.
On Tuesday, taxi driver Zola Tongo told Western Cape High Court he was offered 15,000 rand (£1,400) by Shrien Dewani, 31, from Bristol, to kill his wife.
Mr Dewani was arrested on suspicion of conspiring to murder his wife.
He is due to appear before the City of Westminster magistrates later, the Metropolitan Police said.
Mr Dewani arrived at the court house in a police van just before 1100 GMT on Wednesday.
His family have described the allegations as "totally ludicrous".
Scotland Yard said Mr Dewani, from Westbury-on-Trym, had been arrested in the UK following an extradition request by prosecutors in South Africa.
The South African justice department said it would initiate full extradition proceedings when it had received further documentation from prosecutors. BBC News
