By Shashwat Chauhan Aug 30 (Reuters) - European shares struggled for direction on Wednesdayas losses in utilities, led by Denmark's Orsted, kept a lid on gains, while insurers rose on positive results from Prudential. UK's FTSE 100 .FTSE outpaced regional peers, rising 0.4% as PrudentialPRU.L climbed 3.8% after the Asia-focused insurer posted a higher first-half operating profit. Euro zone bond yields rose after data from the German state of North Rhine-Westphalia (NRW) showed a rise in inflation, supporting expectations that the European Central Bank's tightening cycle might not end soon.
