Labour leader Ed Miliband has awarded junior shadow ministerial roles to a third of his party's newest MPs.
His "new generation" of frontbenchers includes 23 of the 66 MPs who were elected in May.
They include new parliamentary private secretary to Mr Miliband, Chuka Umanna, 31, and Michael Dugher, an ex-special adviser to Gordon Brown, at defence.
Mr Miliband said experience also counted and made Jack Dromey, 62, a shadow communities minister.
The former trade union leader is the husband of deputy Labour leader Harriet Harman.
Mr Miliband said: "I am particularly pleased that I could bring in a new generation of talent, whilst also using the experience of a broad range of Labour MPs.
"This is a team from all parts of the party, which will robustly hold the coalition government to account."
Other new MPs given shadow ministerial roles on Labour's list include John Woodcock (transport), who worked for Mr Brown at Downing Street, former TV journalist Gloria De Piero (culture) and 28-year-old Luciana Berger (energy).
Leadership contender Diane Abbott had already been named shadow minister for public health.
