The embattled Liberal Democratic Party is losing support among doctors, traditionally key supporters of the ruling party, ahead of the Aug. 30 general election, a Kyodo survey said Saturday.

The survey found that the number of prefectures in which doctors' groups plan to back LDP candidates in all electoral constituencies has dropped to 19 from 29 in the previous Lower House poll taken in 2005.

Particularly notable is Ibaraki Prefecture, where a doctors' group has recommended candidates from the Democratic Party of Japan in all seven constituencies.
