On Thurday's Question Time, there was one politician notably absent from the panel. For a second time, John McDonnell, the shadow chancellor, had to cancel his appearance -- this time putting it down to train delays. And whose fault is this? Well, the Conservatives obviously -- as if Labour were in power the trains would be nationalised:

However, there's a problem. First, those flights sold out after Mr McDonnell had been booked on a flight - but he arrived at the airport too late and the gate was closed. So you can't really blame privately-owned railways for that.

More importantly the delays in question were caused by a train caught up in overhead lines, and being left there for far too long. The track and those wires are managed by Network Rail, which is already nationalised.

What is it about the he Labour leadership and public transport accusations? Given that Jeremy Corbyn's traingate PR stunt last year also backfired, Mr S would advise the pair to give it a rest.
