Court normally on summer recess in September
The chief minister has written to the President of Tynwald to ask for the court to be recalled on 13 September.
Alfred Cannan says it would enable government to set out its response to the rising cost of living.
Politicians have met privately today to consider future support.
The chief minister says good progress is being made on a package of measures to help people through the winter into 2023.
It's hoped details will be announced on Thursday 25 August.
Tynwald doesn't usually sit during September because of the summer recess.
The chief minister said:
“I want to reassure the public and the business community that Government is aware of the anxiety many are experiencing over the rising cost of living, especially concerns around energy price increases due this winter.
“I have today written to the President of Tynwald on behalf of the Council of Ministers to request that he consider calling an extraordinary sitting of Tynwald on Tuesday 13 September. This will enable Tynwald to discuss the cost of living pressures and for Government to set out its response.”
Update at 5.35pm: President of Tynwald Laurence Skelly has confirmed Tynwald will sit at 10.30am on Tuesday 13 September. He says "The purpose is to discuss the cost of living crisis and the Government’s outline response."
