Prosecutors have received key emails in the Chris Huhne speeding case and a decision on whether to charge the Energy Secretary is expected to be taken within weeks.
The Sunday Times dropped its challenge to a court ruling ordering evidence to be disclosed last Friday.
The material is believed to include exchanges between the newspaper's political editor and Mr Huhne's ex-wife, Vicky Pryce, over allegations that she accepted penalty points on his behalf.
The Crown Prosecution Service (CPS) confirmed today that lawyers have taken possession of the material from Essex Police and begun reviewing it.
The force has been investigating the case, which relates to a speeding offence in March 2003, for eight months. An initial evidence file was delivered to the CPS last July.
The Liberal Democrat Cabinet minister has repeatedly denied any wrongdoing.
An Essex Police spokesman said: "We have shared the material we have received with the CPS.
"Officers will meet with them to discuss this in the next few days, as we said we would."
