As a Millwall season ticket holder, I am supposed not to care that no one likes us.

Peter Ramage London Reading of HS2’s current start and end points being cut short (Report, 18 September) reminds me of the M1 opening some 60-odd years ago, which started well north of Hendon and ended south of Coventry, but was billed as the London to Birmingham motorway.
