Photograph: Metropolitan police/PA A man who was jailed for 13 years for trying to blow up an airliner with a shoe bomb has had his sentence cut after agreeing to give evidence against other suspected terrorists, police and prosecutors have said. Saajid Muhammad Badat, who was jailed in 2005, had his sentence reduced to 11 years in 2009 as part of a deal with prosecutors, it can now be reported. It is the first time a terrorist convicted in the UK has entered into an agreement with the Crown Prosecution Service to give evidence in a trial against other alleged terrorists. Sue Hemming, head of the CPS special crime and counter-terrorism division, said the agreement had not been entered into lightly. It will see Badat give evidence in the US trial of Adis Medunjanin over an alleged al-Qaida martyrdom plot from 2008 to 2010, which opens in New York on Monday. "We considered very carefully the merits of entering into this agreement with a convicted terrorist, and we believe that the administration of justice internationally benefits from such an agreement," she said. This trial is the first time a UK convicted terrorist has agreed, under the terms of our agreement, to give evidence in the United States. Badat has helped with investigations in this country, he continues to co-operate and has agreed to testify in other trials if called upon.
