The annual rate of inflation increased by 5.1 per cent in the year to October, the latest Consumer Price Index (CPI) update showed.

Figures from the Central Statistics Office (CSO) revealed October's annual rate was down slightly on September's figure of 6.4 per cent.
Despite the fall, last month's figures showed a continuing trend of annual CPI growth of over 5 per cent, as it has been since October 2021.
Excluding energy and unprocessed food, the annual CPI was up 6.3 per cent in October.
On a monthly basis, inflation rose by 0.3 per cent between September and October, with the biggest changes noted in the Education and Transport sectors, where prices jumped 2 per cent and 1.1 per cent respectively.
Annually, costs were up across all divisions compared to October 2022, with Recreation & Culture showing the largest increase as prices jumped 9.7 per cent.
The Restaurants & Hotels sector noted a 7.7 per cent increase in costs, followed by Housing, Water, Electricity, Gas & Other (up 7.2 per cent), and Food & Non-Alcoholic Beverages (up 7 per cent).
