Speaking on Channel 4 News over the past few days, the Deputy Prime Minister of the Republic of Ireland, Simon Coveney, said that it was ridiculous to argue that one could avoid a hard border if there is a 'no deal' Brexit. He said that 1,077 additional customs officials and veterinary inspectors and security officers would need to be employed in airports and ports to deal with trade east to west. Isn't it inevitable in such circumstances that huge damage will be done to trade through the port of Holyhead in my constituency? Doesn't that demonstrate how irresponsible the supporters of a hard Brexit are within the Conservative Party and how irresponsible Labour under the leadership of Jeremy Corbyn has been in not having insisted from the outset that there would have to be membership of the single market and the customs union?
