He was a Labour Member of Parliament in Glasgow from 1962 to 1983.
Carmichael represented Glasgow Woodside from a by-election in 1962 to February 1974, then Glasgow Kelvingrove.
For the 1983 general election his constituency was abolished and merged with GlasgowHillhead which had been won in a byelection by Roy Jenkins for the SDP.
