Vicky Pryce's lawyer Robert Brown has read a statement to waiting reporters on behalf of the mother-of-five, following her release from prison.
He said: "Vicky Pryce is very pleased to be home and back with her family. She is grateful for all the support she has received from everyone whilst in prison, including her fellow residents and prison staff.
"She now intends to spend time with her family and looks forward to returning to her career as an economist."
Pryce, who will have to wear an electronic tag, has ideas to write about the economics of the criminal justice system, combining her economic expertise with her experience behind bars, but has not so far written a book on it, according to Mr Brown.
The Greek-born economist was jailed after being convicted of perverting the course of justice after a retrial at Southwark Crown Court.
During her trials, the court heard she had revealed the speeding points scandal to newspapers in 2011 in a bid to "nail" her ex-husband, who had left her the previous year for PR adviser Carina Trimingham.
