The president of the Chega party said he is willing to support a Socialist Party proposal. Chega's backing could help the measure gain support among legislators. The proposal would exempt capital gains from tax on house sales of up to 300,000 euros. The statement also asks Socialist deputies to approve the proposal themselves. It would need votes from beyond the Socialist ranks if it is to advance. Any approval would depend on the final terms and a parliamentary vote. The announcement did not include a timetable or a detailed estimate of the fiscal cost.
