When Stevens is picked up by Jo on the street, he is carrying a briefcase, an attaché case and some papers. After the meeting with Khordad, Ros lets him go with a "Thanks for the cooperation," but none of the items he was carrying are returned to him, so he stands there empty handed.
Stevens read the coordinates out as 51.50295N,0.142264E but both Ros and Malcolm type 51.500295, which gives a point about 320 metres away. Malcolm also says it's the centre of town, but it's actually fairly rural.
The second coordinate Stevens reads out is 0.65378E, but the display shows 0.653378E.
Furthermore, the display shows 53.418295N which puts the point in the middle of the North Sea, east of Lincolnshire and north of the Wash; certainly not in the middle of London.
Connie James claims that thousands died during the bombing raid on Coventry on November 14th 1940.
While in reality fewer than 600 people died.
At Liverpool Street station, Lucas pucks up a Metro newspaper.
All the station departure boards showed 16.00+ times.
The Metro is a morning newspaper: at that time of day the newspaper stands should have held Evening Standards.
In the opening scene, Lucas North is seen walking around inside Liverpool Street Railway Station whilst meeting a contact. However, a cutaway shot at one point shows the platforms at London Bridge Station, which is a very different station located on the other side of London.
The bomb's location is shown as 52.696589N, 0.789559789E which is not in London, but in the middle of Norfolk north-east of Swaffham.
