Overview

• Downing Street rejected claims that ministers, advisers or concerns over investment influenced the CPS decision and Sir Keir Starmer said he has full confidence in national security adviser Jonathan Powell.
• Security minister Dan Jarvis told MPs the deputy national security adviser provided three witness statements under the old Official Secrets Act framework and said outdated law and prior policy constrained what could be said.
• MI5 issued new guidance to MPs, peers, candidates and parliamentary staff warning they are potential targets for state espionage and setting out protective steps at home and on overseas travel.
• Commons Speaker Lindsay Hoyle voiced anger over Parliament's protection and said he is considering a private prosecution in the wake of the collapsed trial of Christopher Cash and Christopher Berry, who deny wrongdoing.
• Senior Conservatives wrote to the director of public prosecutions to ask whether the case could be restarted if ministers now provide the specific evidence the CPS had requested.
