BORIS Johnson will help launch Gavin Barwell's reelection campaign at Fairfield Halls tonight.
The Mayor of London heads a list of speakers including John Burton, Westfield's director of development, and Jonny Rose from Croydon Tech City.
Around 300 people have applied to attend the event, the Advertiser understands.
Mr Barwell will hope the rally can help him claw back some of the momentum lost to Labour following the Conservative's defeat in May's local elections, in which the party lost ground in several key areas of Croydon Central.
Boris's involvement raises the profile of the event, but the presence of several prominent members of the community will have his main opponent next May - Labour's Sarah Jones - more worried.
Mr Burton is a prominent part of the team leading the £1 billion joint redevelopment of the Whitgift Centre by Westfield and Hammerson.
Mr Rose's involvement will lead to suggestions that Croydon Tech City - a group representing and promoting the borough's burgeoning technology sector - is endorsing Mr Barwell's reelection campaign.
He will be followed by knife crime campaigner Eliza Ribeiro; Maureen Martin, executive head teacher of the Coloma Trust, a group of schools set up by Coloma Convent Girls' School; and Rosina St James, chairman of the British Youth Council and a former Conservative local election candidate.
Mr Barwell said he wanted the event to be as non-political as possible and to highlight some of the "good things happening in Croydon" during his time as MP.
The campaign launch begins at 6.30pm.
