By Jan Lopatka PRAGUE, June 29 (Reuters) - The Czech government agreed under court pressure on Monday to let President Petr Pavel attend a NATO summit in Turkey next week but refused to allow him to lead the country's delegation, laying bare their rift over defence spending. Ankara will host 32 NATO leaders on July 7-8, amid tensions over burden-sharing, defence spending, and U.S. complaints about allies' lack of involvement in re-opening the Strait of Hormuz.
