Shadow health minister Andy Burnham was due in Blackpool today to speak at the annual conference of shopworkers union USDAW.
Around 1,300 delegates were set to attend the four-day conference at the Winter Gardens which ends tomorrow.
Mr Burnham is the keynote speaker in the event’s Politics Debate.
Shadow home office minister Jack Dromey is also due to attend today, to address a fringe meeting.
Usdaw General Secretary John Hannett said: “Our annual delegate meeting is effectively the union’s parliament and provides lay-members with the opportunity to raise their issues of concern and make our policy.
“This year we have a packed agenda and it is clear from the issues raised that members are very concerned about the cost of living.
“While the Government is hailing a recovery in the economy, I am afraid our members are not yet feeling the benefit.”
