The family of a pregnant Scottish woman who died in Ghana hope a UK inquest will provide answers to questions surrounding her death.

Charmain Adusah, who was from Arbroath in Angus, was found face down in the bathtub of a hotel in March 2015.

A post-mortem revealed the 41-year-old died of a heroin overdose but her family have voiced serious doubts about how the drug got into her system.

They say they are "stunned" the trial against her husband Eric Adusah has been dropped by Ghanaian prosecutors.

Her mother Linda Speirs confirmed she has received a letter from the HM Coroner's Court in Essex saying an inquest into the death will be held in August.

She told STV News the long-awaited results of the post-mortem examination in the case are expected later this month, which will go on to form part of the inquiry.

It will also look at information provided by authorities in Ghana.

Mrs Speirs said: "We are hoping they can find something to explain what happened to Charmain. We need answers, there are still so many questions we have about how she could have died.

"She was happy and healthy and looking forward to becoming a mum again. She would never have touched drugs so we just can't explain how she could have died. We have grave suspicions and were shocked when the charges were dropped in Ghana.

"We hope now that it's being looked at in the UK we can finally get some answers."

The 41-year-old married evangelical preacher Mr Adusah in September 2014. The couple were visiting Koforidua for the funeral of Mr Adusah's father when she died.

Last October Mr Adusah, who was the head pastor at the Tottenham branch of Global Light Revival Ministries in London, was released from court after the charge against him was dropped.
