Joan Collins has denied that she was arrested in the Republic of Ireland.

Irish politician Joan Collins was arrested at a protest against new water meters in Dublin on April 20.

Actress Joan Collins has taken to Twitter saying: “No I am not the Joan Collins Who was a rested (sic) yesterday At a Dublin protest meeting !!! The very idea !!”

United Left TD Joan Collins said she was taking part in a “peaceful protest”.

The politician later tweeted that she should not be confused with the British actress.

“For the record I’m not @JoanCollinsOBE as I’d never take an honor from a monarch nor did I wear shoulder pads in the 80s. The very idea!”

Joan Collins, 81, was made a dame in the Queen’s New Year’s honors list in 2014.

She was previously a patron of UKIP, but said that does not mean she would vote for them, and has declared herself an admirer of former PM Margaret Thatcher.

Irish parliamentarian Joan Collins sits on the opposite end of the political spectrum.

Joan Collins was among 13 people arrested at the demonstration, which was part of continuing protests against the introduction of water charges in Ireland.
