British citizen Andargachew Tsege, who was freed by the Ethiopian authorities in May after spending four years on death row, has told the BBC he was not allowed a pen a paper while in jail.

Whilst inside he knew nothing about what was going on in the outside world – and only his 90-year-old father was allowed to visit him.

He did not know about the campaign for his release, mainly led by his partner Yemi Hailemariam, or the political turmoil in the country.

The government had accused him of plotting a coup and had sentenced him to death in absentia in 2009.

He was then apprehended at an airport in Yemen while in transit and turned over to the Ethiopian authorities.

Mr Andargachew came into BBC Focus on Africa's studio in London to discuss the first 100 days in office of Prime Minister Abiy Ahmed, whose reforms have seen the release of thousands of political prisoners.

Mr Andargachew, a father of three, fled Ethiopia in the 1970s and sought political asylum in the UK.
