The gardening leave period will be whatever is detailed in his present contract, I didn't realise you have access to his contract with the BBC ?
I do have access to UK employment law though.
Considering that is next Monday it's safe to say no. Even if the BBC put him on "gardening leave" immediately based on previous transfers it's still likely to be some time before he appears on ITV - legally the BBC can enforce a notice period of one week for every year he's been employed by them, so I doubt we'll see him on ITV News before Christmas.
