Simon Danczuk was arrested and put in a Spanish jail cell after an alleged holiday row with his estranged wife led to her being taken to hospital, it was reported today.

Karen Danczuk, 33, reportedly suffered cuts and bruises in the incident in Alicante which is believed to have taken place on Sunday night after the Labour MP arrived to join Ms Danczuk and the pair’s two young sons at their apartment.

According to The Sun, witnesses said the MP, who is currently suspended from the Labour party pending an investigation into sending lewd text messages to a teenager, snatched Ms Danczuk’s phone and threw it in the pool, screaming: “I just want to talk to you” as he was led away by police.

An onlooker told the newspaper: “There was an almighty row and he seemed very drunk. Then he grabbed her phone and thew it in the water. She retrieved, went indoors and shooed him out. He began banging and screaming.”

A neighbour said: “The whole neighbourhood was awake. Some got so concerned they ran over to intervene. Karen appeared to have a large cut to her chest. I think she had been cut by glass shattering. It looked quite nasty.”

Rochdale MP Mr Danczuk, 49, recently said he needed therapy for sex addiction after admitting he had sex with a 22-year-old woman in his constituency office.

Neither has responded to requests for comment.
