This is not an April Fool’s joke either.

Remember how a week ago, as Mayor of London Boris Johnson leapt on a Croydon Tram to try to prove he was not off his trolley by announcing that, if re-elected in next year’s elections, he would see to it that the Tramlink extension to Crystal Palace would be built?

Transport for London this week published its four-year plan for public transport in the capital. The Crystal Palace Tram extension? Not a word.

Do you think Boris – who less than three years ago decried the previous London administration’s plans for a Crystal Palace Tram extension as an “unrealistic and hollow promise” – was hoping no one would notice?
