However, three sitting SDP members of parliament — Owen, John Cartwright, and Rosie Barnes — did not join the SLD, opting instead to create a new 'continuing' Social Democratic Party.
A party conference at Paisley Town Hall in 1989 was held behind closed doors without the usual television coverage to conceal the rows of empty seats.
A shortage of members left the party exposed to electoral embarrassment if it stood candidates in areas where there was a lack of activists to bring out the vote.

When the SMF became more closely associated with the Major Government following the 'continuing' SDP's demise in 1990, Skidelsky, Finkelstein, Cooper and Nye all joined the Conservative Party.

However, the party found itself unable to get any significant media attention, vital to compensate for a lack of activists at local level.
John Cartwright and Rosie Barnes stood under the "Independent Social Democrat" banner they had adopted in the House of Commons, defending their seats in Woolwich and Greenwich respectively.
