A first-half goal from Wilfred Ndidi and Jamie Vardy’s 15th league goal of the season proved enough to secure a priceless victory for Enzo Maresca’s side.
Jed Wallace halved the deficit for West Brom in a game where they created the best opportunities, Hamza Choudhury incredibly making three goalline clearances, but they were unable to earn the share of the spoils that they deserved.
The East Midlands outfit now sit two points clear of second-placed Ipswich Town and, more importantly, four points ahead of third-placed Leeds United with three matches remaining.
Meanwhile, West Brom remain in fifth spot in the standings with just two matches left, Carlos Corberan’s side hoping that results go their away in order to feel more secure of a top-six place.
Leicester went into this contest considerably low on confidence given their recent form, and that almost contributed to an opening goal being conceded within three minutes, Okay Yokuslu blazing wastefully off target after a mix-up between goalkeeper Mads Hermansen and Choudhury.
Before the quarter-hour mark, Choudhury had to get back to clear a Mikey Johnston effort off the line, before the Baggies winger forced a save out of Hermansen with a low drive.
While the Foxes had been second best, they were ahead in the 22nd minute. After West Brom goalkeeper Alex Palmer had saved a Vardy header, Ndidi reacted quickest to slot home the rebound.
