An Post has been urged to exhaust all avenues to retain its office in Clare's second-largest town. The contract for Shannon's Post Office went up for tender last week following the resignation of its Postmaster. A procurement process to find a new operator is open until September 26th. Newmarket-On-Fergus Fianna Fáil Councillor David Griffin has written to An Post on the matter, he says it's a crucial community asset.
