The Tube map that features Yitzhak Rabin
The London Transport Museum has an exhibition of artworks inspired by the familiar map of the Tube.
One design, by Simon Patterson, instead of underground stations lists the names of famous, and not always so famous, people down the ages.
On the Northern Line replacing London Bridge station is Israeli Prime Minister Yitzhak Rabin, who is three stops north of Leon Trotsky, eight from Egyptian President Anwar Sadat and nine from American Jewish radio host Alan Berg.
The entries on each line are connected by a theme. Can you guess what links those on the Northern Line?
They were all assassinated.
