German media group Axel Springer has agreed to buy the owner of Britain’s Daily Telegraph newspaper for 575 million pounds ($766 million). The agreement was announced Friday by the two groups. It ends a long saga over ownership of the Telegraph Media Group, which publishes the 171-year-old Daily Telegraph and its Sunday sister paper. Axel Springer said it will invest in the group “to enable it to become the leading center-right media outlet in the English-speaking world.”
