A senior Conservative aide has described how she had to buy size 14 trainers for former England footballer Sol Campbell when he forgot to bring suitable footwear while visiting a key constituency for the party in 2015.
Asked by her defence counsel Jim Sturman QC to tell jurors about Mr Campbell's visit to the Kent seat, Little said he had "forgot to bring his trainers" and was due to attend a children's training session afterwards.
She agreed with Mr Sturman it was "not easy" to find size 14 trainers in south Thanet at short notice, but did so and paid for them out of her own pocket.
She added: "He (Mr Campbell) was down there as a Conservative supporter and volunteer.
"I think he was interested in being a candidate for the (London) mayoral campaign."
Mackinlay, from Ramsgate, Kent, denies two charges of making a false election expenses declaration under the Representation of the People Act 1983.
A third defendant, 29-year-old Tory aide Nathan Gray, of Hawkhurst, Kent, denies one like charge.
The trial continues.
