A top Lewisham UKIP politician called a critic a c**t in an astonishing foul-mouthed online outburst.

Potty-mouthed politician Matt Pavey, who stood for election in Lewisham's Whitefoot ward at the last local elections, used the swear word during a heated exchange on Twitter.

His outburst comes after a party parliamentary candidate resigned over the weekend following offensive remarks he blamed on strong painkillers.

Mr Pavey was told by Twitter user Liam McPeake today: "Stop taking strong painkillers, the side effects are showing."

The UKIP man replied: "You've no idea how hilarious I found your idiotic comment being as I am in constant pain and rely on medication."

After a further exchange, Mr McPeake told him: "Haha, just take your medication and rant like the rest of your colleagues. #UKIPexcuses."

Mr Pavey ranted: "You sire, are a C**T. You disgust me thinking it's acceptable to take the piss out of others disabilities!"

Afterwards, he tweeted to his followers: "Apologies for swearing folks but the anti #UKIP brigade laughing at my medical condition/constant pain was too much!"
