Suicide rates behind bars remain at an "alarmingly high level" as eight people took their own lives in the West Country alone last year.
Figures show four people took their own lives in Exeter prison, while two more died in Guys Marsh in Dorset. Deaths by suicide were also recorded in Dartmoor and Erlestoke prisons.
As the number of prisoners grow annually, and chronic overcrowding and staff cuts hit systems hard, deaths by suicide have risen by 46 per cent in the last three years.
The figure is among a total of 29 people who committed suicide across the country, with a further eight prisoners killed in apparent homicides during 2015 - the highest number in a single year since current recording practices began in 1978.
The Howard League for Penal Reform and Centre for Mental Health, supported by The Monument Trust, are working together on a joint programme on preventing people from dying by suicide in prison.
They saw around 40 per cent of prisoners who died by suicide in 2015 were on remand at the time of their deaths - despite people on remand make up only 15 per cent of the prison population at any one time.
Evidence suggests people held in prison on remand, or have been recalled while on licence, are disproportionately likely to take their own lives.
A rally is planned to coincide with transgender woman Tara Hudson's appeal to be moved to a female prison.
The appeal will be heard at Bristol Crown Court tomorrow (Oct 30) and supporters have arranged to protest outside.
Transgender woman Tara Hudson was sent to an all-male prison in Bristol after admitting to assault.
She has lived all her adult life as a woman and has undergone 6 years of reconstructive surgery. Prison authorities made the decision to send her to HMP Bristol as her passport states she's a man.
An online petition calling for Tara to be moved to an alternative facility has reached over 100,000 signatures in 3 days.
A Facebook event calling for an 'emergency protest' outside the Ministry of Justice in London has also been set up.
A damning report into Guys Marsh prison in Dorset has found managers and staff "all but lost control of the prison".
An unannounced inspection by HM Inspectorate of Prisons in November 2013 found levels of violence at the jail were very high and the violence was driven by the supply of drugs.
- levels of violence in the prison were very high and many prisoners were frightened.
- the violence was driven by the supply of drugs, particularly synthetic cannabinoids such as Spice, which led to debts which were enforced by violence or threats of violence to prisoners or their family outside the prison.
- there had been a number of medical emergencies associated with the consumption of Spice.
- gangs operated openly in the prison, although security staff and managers were well focused on these challenges and worked hard to address them.
- there were frequent ‘incidents at height’ where men climbed onto dangerously high structures in the belief that they would then be taken to the segregation unit where they would be safe.
- some prisoners self-isolated on the wings, hiding in their cells in squalid conditions with abuse shouted through the door.
- the high levels of bullying and debt were linked to high levels of self-harm, although care for men at risk was generally good.
- training provision had deteriorated sharply since the last inspection and the overall effectiveness of learning and skills work was inadequate.
- despite the fact that Guys Marsh was a training prison, only 16% of prisoners were on education or training courses.
- the overall management of resettlement was disjointed and inadequate; and
- offender management was exceptionally poor and arrangements for protecting the public from high-risk prisoners after release were weak.
The inspectors said the prison was short-staffed and overcrowded at the time.
The prison has responded saying it is now stable, operating safely.
Jason Rose, 24, was found hanged in his prison cell while on remand at Exeter Prison in 2011. An inquest into his death heard he had not been put on suicide watch before he died despite previous attempts to take his own life.
An inquest jury returned a verdict of suicide.
The prison service says the circumstances of Mr Rose's death will be looked at as part of a Government review.
The last prisoner is due to leave Gloucester Prison later today - although the prison doesn't officially close until the end of March. The Ministry of Justice says there hasn't been a decision yet on what will happen to the site in the future.
Brian Grady, who escaped prison in Wales last month, has been arrested in Bristol. A man and woman have also been arrested on suspicion of assisting him.
26-year-old Grady was jailed for eleven years in July 2003 after being convicted of killing Liam Attwell in the Canons Marsh area of the city centre.
Following the publishing of the report on Gloucester Prison which claimed the prison had 'stood still' since an earlier visit Nick Hardwick, Chief Inspector of Prisons said:
However, Mr Hardwick went on to say that:
In today's report, Nick Hardwick, Chief Inspector of Prisons said Gloucester Prison has many problems to address.
Inspectors were concerned during their visit in July to find that the environment for vulnerable prisoners at the Category B local prison was poor, and there was evidence that they experienced abuse and intimidation from other prisoners.
Segregated prisoners were not continually supervised, though this was mitigated by low numbers and generally brief stays, while the accommodation was among the poorest in the prison system, and prisoners did not have enough time out of their cells.
There was not enough for prisoners to do and inspectors found well over half of the population locked up during the working day.
A report by inspectors who visited Gloucester prison where concerns had been raised before found that it seemed to have "stood still".
According to the Chief Inspector of Prisons, Nick Hardwick, Gloucester Prison has many problems to address.
