Speedos are never spot on mate.Has the gearbox been rebuilt.A mate of mine has a S1 and he had his gearbox rebuilt and his speedo is a mile out.He can be doing 90 and the speedo reads about 30 lol.

The Focus speedo is normally 3mph out. The Escort on is normally 10%. When you read 70, you are normally doing 66mph. Are you using 15" wheels? If not, then that will make a difference as well.
Someone I know has 17" wheels with 45 profile tyres on his Saff. His speedo is dead accurate, but with 15" wheels, he over-reads by 10%.
