Extensive offer of help from individual Dutch Waterschappen (netherlands has a number of waterschappen (water agencies directly funded by tax payer who have to protect their part of the country through rings of dykes, pumps, sluices, flood plains etc etc)) and the Dutch Ministery of Infrastructure and Environment of extensive practical help and expertise. Practical help in the form of moveable dykes, automated sandbagging machines, more pumps etc etc has all been TURNED DOWN by the UK govt. They have told the Dutch govt they are only interested in expertise.
This is reported in today's Volkskrant on their website.
INCREDIBLE... I would think of all things what is most needed is practical help at the moment.
