Campaign over NFL Redskins’ name gathers pace

US President Barack Obama has joined the fight to change the name of Washington DC’s American football team, the “Redskins”.

The club, one of the biggest earners in the NFL, has held the name for 80 years.

But many Native Americans find it offensive, and their campaign to change what they see as a racial slur is gaining momentum.
