Liberal Democrat leader Sir Vince Cable has condemned US President Donald Trump's tweet after the terror attack on a London train.
Sir Vince told the Lib Dem conference that Britain had the best security services in the world and the US president was out of line to cast aspersions on them.
Sir Vince told delegates in Bournemouth: "The one really discordant part of this whole horrible incident was President Trump's tweet.
"If you noticed this dreadful insinuation that somehow or other our security services were falling down on the job without a shred of evidence.
"I happen to know because I was in the Cabinet for five years, I've worked very closely with them, we have, probably, the best security services in the world."
