As far as I can ascertain the Earl of Wessex attended a service of commemoration for Aethelflaed, Lady of the Mercians (certainly a role model for today if you follow Michael Wood's account of her life) in Tamworth on the morning of June 12th, followed by a reception at Tamworth castle in the afternoon; this was followed by a visit to Sunseekers Shipyard, Poole, in his capacity as Chairman of the board of trustees of the Duke of Edinburgh Award scheme, followed by a Dinner at Brownsea Castle concerning apprenticeship schemes, to attract local businesses to participate. He is spending today and tomorrow promoting tennis activities, again for the DoE Award in Dorset. All quite worthwhile activities, I think.
I would imagine he flew from Tamworth to Poole; the journey from the Midlands to Poole is not easy by train, coach or car at this time of year as I know from personal experience, having done it many times.
