Jon Ashworth MP, Labour’s Shadow Minister without Portfolio, responding to today’s further allegations about Mark Clarke, said:

“It is becoming increasingly clear that the Conservative Party’s response to this affair is inadequate.

"This is a matter of utmost seriousness and David Cameron needs to look at the role of his office in relation to Mark Clarke’s activities.

"No 10 must now provide full disclosure on their involvement in this matter, which to date the Conservative Party has failed to deliver.”
