The previous record of 85,578 was set last month, however there has been an increase of 353 since those figures were calculated, meaning the total now stands at 85,931.
According to the Ministry of Justice, just 2,100 spaces remain until prisons in England and Wales are at full capacity.
Should they be jailed, the Government has insisted there will be enough space for people involved in the recent "looting
" throughout England.
Speaking on behalf of the Prison Service, a spokeswoman said
: "We will always ensure there are sufficient prison places for offenders sentenced to custody by courts.
"There is currently a substantial gap between our available capacity and the actual population at this point.
"New accommodation continues to become available and in the next 12 months 2,500 new places will become operational."
According to the Ministry of Justice as cited by the Daily Mail
, prison capacities have more than doubled since 1980.
