Why does ECB official Martins Kazaks say there is 'no urgency' for another rate hike in July?

According to the news, Kazaks says the urgency for consecutive rate hikes has decreased significantly because peace efforts in the Middle East have lowered oil prices and reduced inflation risks, and the recent energy-driven inflation shock was 'small so far, without risks of nonlinearities and large second-round effects in the labor market.' He adds that 'currently there’s no need to be forceful in our response to inflation' and that price pressures likely eased in June with contained ripple effects from elevated energy costs.

Did Martins Kazaks defend the ECB's June rate hike, and if so, how?

Yes, Kazaks explicitly rejected the idea that the June rate hike was a policy mistake, calling it a 'carefully weighted, robust response to nearly four months of high energy prices' — a decision he defended as justified despite the subsequent easing of inflation risks due to falling oil prices and progress in Middle East peace efforts.
