Norwich South MP Clive Lewis missed his first defence questions in Parliament today because he was still on his way back from Glastonbury.
Mr Lewis, a strong ally of embattled Labour leader Jeremy Corbyn, was appointed shadow defence secretary on Monday morning.
But he was unable to see to his first duty in his new role - attending defence questions in Parliament on Monday afternoon - because he was held up at Glastonbury.
Defence secretary Michael Fallon said: 'I think he is AWOL on his first parade. We will welcome him and pay tribute to his service in uniform. He will be the fourth shadow defence secretary I have seen in two years, I hope he lasts.'
The SNP shouted he was on his way back from Glastonbury.
After the EU referendum result on Friday, Mr Lewis urged Labour supporters to get behind Mr Corbyn.
But he has instead been hit with mass resignations from his shadow cabinet and lost the support of Labour's deputy leader Tom Watson.
Mr Corbyn responded by hastily assembling a new shadow cabinet, but a Labour leadership contest now appears inevitable.
