That marked an increase of half a percentage point from the 1.9 per cent rate recorded in February and was the highest annual inflation rate since October 2014. The Bank's latest forecasts showed inflation peaking at 2.8% by the end of this year although other experts believe an even tighter squeeze looms as the currency's weakness works its way through the economy.

Analysts were expecting CPI to increase to 2.6% and for core inflation to rise to 2.2%.
