Tory peer and pollster Lord Hayward said the result was "disappointing but not bad" for the Conservatives, pointing out that the swing to Labour was smaller than in a recent by-election in Chester.
However, he told Sky News other Tory MPs in the area, including Sir Graham Brady, who represents nearby Altrincham and Sale West and is chairman of the 1922 committee of Conservative backbenchers, would be "concerned".
"There's been a trend away from the Conservatives in that belt of south and west Manchester," he added.
