Labour's Margaret Greenwood retained Wirral West, a marginal seat that was targeted heavily by the Conservatives after Esther McVey was ousted after just one term.
Ms Greenwood won 54.3% of the vote and an increased majority of over 5,000 while Conservative Tony Caldeira came second on 42.1%.
She said she believes Labour have done better than expected because more young people voted.
"People really value public services... and realise that you need a Labour government to get them", she said.
There was a clean sweep for Labour in Wirral as Alison McGovern also held Wirral South, winning 25,871 votes.
