Abid Naseer faces a number of charges including trying to bomb the New York subway and conspiring to commit a terrorist atrocity in Manchester in April 2009.
A court in New York has been hearing evidence from teams involved in the surveillance operation against him.
Rageh Omaar has been at today's hearing in Brooklyn:
He was a war veteran who spent his service on what Winston Churchill called the 'worst journey in the world'.
Gerry Grant, who's now 91 and has lost his sight, was a sailor on the Arctic Convoys in the Second World War.
He and his colleagues braved German U-Boats and extreme cold to deliver supplies to Russia.
Today, almost 70 years later and back home in St Annes, he received the Ushakov medal.
Our Lancashire reporter Victoria Grimes has the story:
The first of five MI5 officers today began giving evidence at the trial of alleged Manchester bomb plotter Abid Naseer.
Officer '1661' wore a beard, glasses and a wig to protect his identity.
Speaking in a Northern accent, he told the court in Brooklyn how he trailed Naseer in Liverpool during late March and early April.
Prosecutors claim Naseer planned to blow up the Arndale Shopping Centre in a bid to carry out a "second 9/11".
He is also accused of planning terorr attacks in New York and Copenhagen but denies the charges against him.
