Pressure intensified last night for a police inquiry into press leaks following the dramatic terror arrests in Birmingham earlier this year.
The Liberal Democrats wrote to West Midlands Chief Constable Paul Scott-Lee asking him to confirm his force would launch a probe into whether the Official Secrets Act had been breached.
And shadow Home Secretary David Davis asked Cabinet Secretary Sir Gus O'Donnell to launch a formal inquiry into news stories which emerged concerning a counterterrorism operation in Birmingham on January 31.
The separate demands from the opposition parties came after Peter Clarke, Assistant Commissioner of the Metropolitan Police and Britain's most senior counter-terror police chief, warned this week that leaks in anti-terror operations "put lives at risk" and "undoubtedly raised community tensions".
Earlier yesterday Tony Blair rejected calls for an inquiry as he clashed with Conservative leader David Cameron in the Commons over alleged briefings to the media following the arrests of nine men in February.
In the days immediately after the raids, it was reported officers had foiled a plot to kidnap, torture and behead a British Muslim soldier.
At the time, West Midlands Police complained the leaks into their ongoing investigation were damaging community
relations. Birmingham MP Khalid Mahmood (Lab Perry Barr), chair of the All-Party Parliamentary Group on Tackling Terrorism, said there was no need for an investigation.
He said: "Inquiries look at what happened in the past, but what is important is putting procedures in place to ensure it doesn't happen again in the future.
"There have been too many cases of information being leaked and the credibility of the police may be called into question if this continues."
