Sir David Davis said Mr Lynch, who died along with six others in the superyacht disaster off Sicily last week, "saw straight through the statistical weaknesses that underpinned the Letby prosecution".
The Conservative MP and the businessman had been due to meet last Thursday.

Letby was jailed for life after being convicted of the murders of seven babies and the attempted murders of six others at the of Countess Chester Hospital.
Sir David said: "The toll on Mike was immense, but so was the relief when he was acquitted in June. That's what makes last week's cruel turn of events ever more tragic.
