Ann: Full Year Statutory Accounts, page-7

Typical... left open to interpretation but to me it still sounds like they've got rid of the issues and are looking to demo "...present a positive outlook on the company’s ability to reach in a timely manner, its next critical milestone involving demonstrating our technology". Being blunt, a timely manner would be considered by a sane person to be per the timeframe previously communicated, which is still possible but the "positive outlook" phrase implies a less than definitive demo date. So I take this to mean they'll miss it by a couple of weeks.
