César Strawberry has found it hard to concentrate on his music recently.

The singer found fame in Spain with rap-rock band Def Con Dos and their notoriously explicit lyrics.

But his controversial commentary has also brought him into direct conflict with the Spanish state.

"It's a co-ordinated strategy aimed at making people scared of speaking out, of expressing themselves and at cutting back a system of freedoms," says Strawberry.

"Sadly, in Spain the government of Mariano Rajoy has embarked on a path which seeks to copy Turkey, rather than France, Germany, Britain or Sweden."

In 2017, Strawberry received a one-year jail sentence for glorifying terrorism and humiliating terrorism victims in what he claims were some humorous Twitter posts - one suggested giving the king a "cake-bomb" for his birthday.

The 54-year-old has not gone to jail because in Spain sentences of less than two years without a prior conviction are usually suspended.

But he believes his country's government and justice system have embarked on a campaign to slash basics rights of freedom of speech - and that musicians like him are among the main targets.
