Long-standing Purplebricks critic Chris Wood is to speak at the UK Investor Show this Saturday at the invitation of share tipster and ex-fund manager Tom Winnifrith.

Describing himself as the “estate agent who takes on Purplebricks”, Wood is due to be the final speaker at the event, held at the QEII.

Winnifrith said that Wood will “blow the lid” on Purplebricks and will deliver “sensational new material”.

He added that “if Purplebricks sends us a lawyer’s letter we will not back down”.

Wood tweeted: “Looking forward to meeting Purplebricks UK  lawyers face to face as I’m guessing they’ll be showing up.”

Wood told EYE: “I’m going to be tailoring what I have already written in my blogs plus a few new items and thoughts to the specific audience I’m speaking to.”

Purplebricks declined to comment.
