TALLINN (Reuters) - Estonia's centre-right prime minister claimed victory in an election on Sunday, cementing pro-NATO policies after a campaign dominated by fears of interference by neighbouring Russia following Moscow's annexation of Ukraine's Crimea region.

Taavi Roivas' Reform Party won 28 percent, ahead of 25 percent for the opposition centre-left Centre Party which wanted Estonians to embrace a new policy of better relations with Moscow to ensure security for the small Baltic state.
