Broker with lowest spread on Corn (CFDs)?

Hi everyone

I am looking for a broker with the lowest spread on corn (CFDs contracts)

I know that Alpari UK offers 6-tick spread (6 * 0.25)

Do you know other CFD brokers?

Thanks

Check IG Markets UK
They offer 4-5 ticks as far as I remember

Ok, thanks

I used to trade with GFT UK but their spread is too high, 9-10 ticks.
