Several bookmakers have suspended betting on who will headline Glastonbury in June after a cryptic tweet from former Oasis member Liam Gallagher.

At 10am Thursday morning, Gallagher tweeted the letters O A S I S one by one before tweeting the whole word "OASIS".

This final tweet was re-tweeted over 30,000 times and bookmakers Paddy Power slashed Oasis's odds to 1/3 just three minutes later. By 10.45am Paddy Power had suspended betting completely.

This morning, Ladbrokes tweeted that they were still taking bets at 4/5.

Arcade Fire are the only headliners already announced.
