Spanish 12-month inflation rose to 10.2% in June, the first time it surpassed 10% since April 1985, up from 8.7% the previous month, preliminary data from the National Statistics Institute (INE) showed on Wednesday.

The reading was higher than the 9.0% forecast by analysts polled by Reuters.

Core inflation, which strips out volatile food and energy prices, rose to 5.5% year-on-year from 4.9% a month earlier, the INE data showed.
