Admitting to an alcohol problem, Danczuk said he was "lonely" and "drunk" when he sent the messages
Simon Danczuk has apologised for "letting my family down" after being suspended from the Labour party for sending sexually explicit text messages to a teenage girl.
The Labour MP for Rochdale told The Sun on Sunday newspaper that he was "lonely" and "drunk" when he sent the messages while on a holiday in Spain.
"I have a drink problem, and that is a major contributory reason why I sent the messages," he said.
"I've seen a psychiatrist about it and he's told me to stop drinking for six months.
"I feel awful about what happened. I don't know what came over me. I'm so embarrassed that I've been such an idiot.
"I'm sorry for letting my family down and I'm already dreading my young sons finding out when they are older."
The 49-year-old was suspended from the Labour Party pending an investigation into the messages, which were sent to teenager Sophena Houlihan.
Ms Houlihan, who is now aged 18, said Mr Danczuk sent her numerous messages after she contacted him about a job.
The pair exchanged messages for nearly a month before Mr Danczuk asked how old she was, according to a report in The Sun.
Mr Danczuk earlier responded to the claims on Twitter, saying: "Today's Sun story, while not entirely accurate, refers to an extremely low point in my life."
He also tweeted: "My behaviour was inappropriate & I apologise unreservedly to everyone I've let down. I was stupid & there's no fool like an old fool."
Mr Danczuk has previously spoken about how his work to expose child sex abuse had left him depressed and he was receiving psychiatric treatment.
