Bold Seagull
strong and stable with me, or...
The son of a father who for a while was very anti-EEC/EU but strangely became a keen supporter when offered a nice pay package from them !
He was pro-EU / remaining when he led the Labour Party. So when you say 'become' a keen supporter when offered a job with them, he had led Labour manifestos promising to work with the UK in the EU decades prior to that.
