Leadbeater was a right-handed lower order batsman, and a leg-break and googly bowler, who had a couple of good seasons for Yorkshire in 1950 and 1951, but failed to keep his place in the side.
He reappeared for Warwickshire County Cricket Club in 1957 and 1958, as a possible replacement for Eric Hollies, who retired after the 1957 season; but he failed to take enough wickets and his contract was not renewed.
His selection to replace Derbyshire's injured Bert Rhodes on the 1951-52 Marylebone Cricket Club (MCC) tour of India, Pakistan and Ceylon was unexpected, and though he played in two Test matches, he was not a success.
Cricket writer, Colin Bateman, noted "Leadbeater was more of an accurate roller, than a traditional leg spinner and his bowling posed few terrors for the Indian batsmen".
[2] Wisden Cricketer's Almanack reported that he modified his action to avoid being too expensive on the tour: however, he was never the same bowler again, and the rest of his first-class career produced fewer than 100 wickets.
