Nick Clegg has said moves to give Cornwall more power is not being delayed – or that the devolution will happen "dreckly".
In the Commons, Stephen Gilbert, Liberal Democrat MP for St Austell and Newquay, deployed the Cornish slang to urge the Government to accelerate plans for local "deals".
Mr Gilbert said: "'Drekly' is a Cornish expression that means doing something maybe some time in the future, possibly never. Can he assure me that in terms of devolving greater powers to the people of Cornwall, drekly is not an answer he will ever give from the Dispatch Box?"
Mr Clegg, the Deputy Prime Minister, who is overseeing city and regional devolution of Whitehall power, told MPs he had never heard the word.
"It is absolutely not our intention to delay further progress on devolving powers and decentralising control over how money is raised and spent across all parts of the UK, including Cornwall," he said.
Plymouth is set to get a "city deal", and a "Cornwall deal" is being worked up as a possible template for rural areas.
