June 9 (Reuters) - UK's FTSE 100 slipped for a third straight session on Thursday, after the European Central Bank signalled it will hike euro zone interest rates next month for the first time in a decade.

The blue-chip index ended 1.5% lower with healthcare and financials leading losses and the midcap FTSE 250 index slipped 1.2%.

Markets have been anticipating the ECB's decision for weeks, and the prospect of a greater rate hike in September impacted sentiment at a time when the euro zone economy is struggling with slowing growth and rising inflation.

"While the ECB did not take any action today, the outcome of today´s meeting had a distinctly hawkish tone," said Silvia Dall´Angelo, senior economist at Federated Hermes Limited.

"Overall, it makes sense for the ECB to embark on a gradual normalisation path. Most recent data - the PMIs surveys, notably - suggest the recovery has continued, despite the shock from the war."

The focus now shifts to U.S.

inflation data due on Friday, with the Federal Reserve expected to continue with a 50 basis point rate increases at its meeting next week and again in July.

British short- and medium-dated government bond yields rose sharply after the European Central Bank's decision, kekar4d prompting markets to bet on faster tightening by the Bank of England too.
